Do groups or periods have similar physical and chemical 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.
Why do elements belong to the same group show similar chemical properties?
Solution. Chemical properties of elements depend upon their valency. Elements belonging to the same group have the same valency. Hence, the elements belonging to the same group show similar chemical properties.
Do elements in the same group have the same chemical and physical properties?
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).
Why do elements belong to the same group have similar chemical properties?
(a) (i) All the elements of a group have similar chemical properties because they have the same number of valence electrons in their outermost shell. (ii) All the elements of a period have different chemical properties because they have different numbers of valence electrons in their atoms.
What is similar between elements in the same group?
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.
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.
How are elements in the same period similar?
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.
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.
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.
Whats the difference between a family of elements and elements in the same period?
Summary. 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.
How do you find the period and group of an element?
If you are given with the atomic number of an element you can find it’s period number and group number. The period number is related to the number of electron occupied shells in the element and the period number is linked to its valence electrons.
Are elements in the same group in the same family?
Here’s a look at the difference between a family and a group. For the most part, element families and element groups are the same things. Both describe elements that share common properties, usually based on the number of valence electrons.
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.
Which elements are in the same group?
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.
What defines a group of elements?
group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts.
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.
Do elements in the same group have the same number of protons?
All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons.
How many periods are in the periodic table of elements?
The periodic table of the elements contains all of the chemical elements that have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthanoids (lanthanum, 57, to lutetium, 71) and the actinoids (actinium, 89, to lawrencium, 103) indicated …
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.
How do you find the period?

How do you find the period and group of elements in Class 10?
- If the element is in s block, then the group number is equal to the number of valence electrons. …
- If the element is in the p block, then the number of the group can be determined by the formula: (number of valence electrons + 10).for groups.
4) Why don’t elements in the same periods share many of the same properties? Elements in the same periods have electrons in the same energy level, but it turns out that the energies of the electrons is nowhere near as important as how much elements want to gain or lose electrons to achieve a full octet.
What is period in chemistry?
In chemical bonding: Arrangement of the elements. The horizontal rows of the periodic table are called periods. Each period corresponds to the successive occupation of the orbitals in a valence shell of the atom, with the long periods corresponding to the occupation of the orbitals of a d subshell.
How many groups and periods are in the periodic table?
Groups are the columns of the periodic table, and periods are the rows. There are 18 groups, and there are 7 periods plus the lanthanides and actinides.
What period is the element he in?

What do elements in the same group have in common quizlet?
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.
Do elements in the same group have the same mass number?
The answer is e. number of valence electrons.
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 the relationship between the electron configuration of an element and the period in which that element appears in the periodic table quizlet?
What is the relationship between the electron configuration of an element and the period in which that element appears in the periodic table? The period of an element can be determined from an element’s electron configuration. An elements period corresponds to its highest occupied main energy level.
What does group number tells you about the atoms in that group?
The group number in the periodic table represents number of valence electrons of the elements in a certain group. For example, all the elements in Group−1 have 1 electron in their outer most shell.
What do elements in the same column in the periodic table have in common quizlet?
The elements in the same column of the periodic table are all part of the same chemical family or group. Each member of the chemical family has the same number of valence electrons. Valence electrons are those electrons located in the outer orbital.
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 a period of a function?
The time interval between two waves is known as a Period whereas a function that repeats its values at regular intervals or periods is known as a Periodic Function. In other words, a periodic function is a function that repeats its values after every particular interval.
What is a period in math place value?
A place value chart names each place value. When a number is written in standard form, each group of digits separated by a comma is called a period . The number 5,913,603,800 has four periods. Each period is shown by a different color in the place value chart. The period name is written above each period.
What is a period in a wave?
The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years.
Why are there two different numbering systems for groups?
Unfortunately, there was a slightly different system in place in Europe. To eliminate confusion the International Union of Pure and Applied Chemistry (IUPAC) decided that the official system for numbering groups would be a simple 1 through 18 from left to right. Many periodic tables show both systems simultaneously.
