Why do elements in the same period have similar properties?
Answer: All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law.
What do elements in the same period have in common?
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
Do elements in the same group or period have similar properties?
The elements of a group have similar chemical properties but in a period they have different chemical properties. This is because the chemicals properties depend on no of valence electrons.
Do periods in the periodic table have similar properties?
The filling of each shell corresponds to a row in the table. In the s-block and p-block of the periodic table, elements within the same period generally do not exhibit trends and similarities in properties (vertical trends down groups are more significant).
Why do elements belong to the same group Why do they belong to the same period?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Do elements in a group have similar properties?
Elements in the group have similar chemical properties. This is because their atoms have the same number of electron in the highest occupied energy level.
What elements have similar properties?
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.
Which pairs of elements are in the same period?
Sodium and chlorine are in same period.
How are periods and groups different from each other?
Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.
Why do elements in the same group show similar properties but the elements in different groups show different properties?
The properties of an element depends on the number of valence electrons present in an atom of the element. Elements of a particular group have similar electronic configurations and the same number of valence electrons in their atoms. Hence, all the elements belonging to a certain group show similar properties.
Why does each period have a different number of elements?
Explanation: All the periods in the periodic table do not have the same number of elements in them as the number of elements in a period is determined by the quantum numbers. For example: The first period has two elements only since the 1s orbital gets filled.
How do elements change across a period?
Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
What is the difference between a group of elements and a period of elements on the periodic table?
The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods.
Why are fluorine and chlorine not in the same period?
Explain why fluorine and chlorine are in the same group of the periodic table. They both have 7 electrons in their outer shell, so therefore are both in group 7 of the periodic table, with chlorine directly below fluorine.
Why do elements in a group show same Valency?
Elements In The Same Group Have Equal Valency. This is because these elements comprise the same number of electrons in the outermost shell or its valence shell. As the valence depends upon the valence electrons, they have the same valence.
Which properties are usually identical for elements from the same subgroup?
1 Answer. The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.
Why does each period have a different number of elements quizlet?
The number of elements in a period are different in every period because the number of available orbitals in an atom increases from energy level to energy level. Explain how the atomic mass of an element is affected by the distribution of its isotopes in nature.
How does the periodic properties vary in periods and groups?
In group of periodic table, Electropositivity increases on going from top to buttom in a group. Electropositivity decreases on going from left to right in a period . Answer 2. Atomic radius decrease on going from left to right in a period.
What is the pattern of repeating properties?
A pattern of repeating order is called periodicity. In the mid-1800s, Dmitri Mendeleev, a Russian chemist, noticed a repeating pattern of chemical properties in elements. Mendeleev arranged the elements in order of increasing atomic mass, to form something that resembles the modern periodic table.
How do the electron configurations within the same group of elements compare?
How do the electron configurations within the same group of elements compare? Elements within the same group have the same valence electron configurations.
Why does fluorine and chlorine have similar properties?
What Makes Them Similar? When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.
Which elements belong to second period?
The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
What property is common between the elements fluorine and chlorine?
Both are HIGHLY Electronegative Element and their REACTIVITY is very high. Plus they both are HALOGENS and falls under same group, GROUP 17.
Do elements in the same period have same valency?
i Elements in the same periods have equal valency. ii Valency depends upon the number of shells in an atom. iii Copper and zinc are representative elements. iv Transition elements are placed at extreme right of the periodic table.
Why do elements included in a period not exhibit same valence?
Valency depends on the valence electrons (Electrons in outermost shell). Since in a period number of valence electrons goes on changing, the valency also goes on changing.
What property do all elements in the same group of carbon and the same group of sodium have in common?
Each element within a group has similar physical or chemical properties because of its atom’s outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
Elements in the same group have similar Physical and Chemical properties, they also have the same number of electrons in their outermost shell, the valence shell. All of the elements in a period have the same number of atomic orbitals.
What do atoms of elements in the same group have the same number of?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Which element is in the same period as the element sulfur’s )?
Hydrogen | ||
---|---|---|
Lithium | Beryllium | Oxygen |
Sodium | Magnesium | Sulfur |
Potassium | Calcium | Selenium |
Rubidium | Strontium | Tellurium |
Why don t all the elements in a group have the same properties?
Why don’t the elements within an A group in the periodic table have identical properties? Elements in the same A group do not have identical properties because their valence electrons are in different energy levels.
What do elements in the same period have in common quizlet?
What do elements in the same period have in common? They have the same number of occupied energy levels. What do elements in the same group have in common? They have similar chemical properties and the same number of valence electrons.
Why do different substances have different properties?
Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants.
Can particles of different elements have the same electron configuration?
When two different elements have the same electron configuration, they are called isoelectronic.
What is similar about the electron configurations of elements in the same column of the periodic table?
The same concept applies to the other columns of the periodic table. Elements in each column have the same valence shell electron configurations, and the elements have some similar chemical properties. This is strictly true for all elements in the s and p blocks.
What is common to the electron configuration of elements that belong to the same group?
The elements of a given period have same number of shell and a group have same number of valence electrons in common.
What does it mean if elements are in the same period?
In chemistry, the term period refers to a horizontal row of the periodic table. Elements in the same period all have the same highest unexcited electron energy level or same ground state energy level. In other words, each atom has the same number of electron shells.
Do elements in the same period have the same number of energy levels?
Elements in the main groups ( not transition elements) share the same number of valence electrons. Elements in the same period are filling the same energy level.
How do the following properties vary in a period and in a group of periodic table atomic radius?
Reason: In a period, as we go from left to right, atomic radius gradually decreases. As a result of which the tendency of attraction of nucleus on the bonded pair increases. Hence the values of electronegatvity increases in a period. Reason: As we go from top to bottom in a group, the atomic radius gradually increases.
