Are all atoms of oxygen the same?
No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.
Do all oxygen atoms have a mass of 16?
While most oxgen atoms have a mass of 16 (8 protons and 8 neutrons), a small number of oxygen atoms have a mass of 18 (8 protons and 10 neutrons). Both of these isotopes are stable; they do not undergo radioactive decay. Water molecules (H2O) in the ocean may contain either isotope, oxygen 16 or oxygen 18.
What is the mass of oxygen atoms?
Atomic and Molecular Weights
Thus, oxygen was assigned an atomic mass of 16. We now know that a hydrogen atom has a mass of 1.6735 x 10–24 grams, and that the oxygen atom has a mass of 2.6561 X 10–23 grams.
What do all oxygen atoms have in common?
They are both elements, which are the fundamental building blocks of all matter. This means that they both have protons and electrons. They also both have neutrons. Because they are elements, they are both on the periodic table; carbon is number 6 on the periodic table and oxygen is number 8 on the periodic table.
Are all atoms the same?
Everything in this world are matter and comprises of atoms. But each and every atom is unique. They are not the same at all. Every atom consists of three basic units protons, neutrons, and electrons and these units determine the physical and chemical properties of an atom and matter.
What is the mass of 5 oxygen atoms?
5 moles of oxygen contains 180 grams of oxygen.
Why don t all oxygen atoms have the same mass?
REMEMBER: Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes.

Do all protons have the same mass?
Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron).
How many oxygen atoms are there?
Oxygen is found naturally as a molecule. Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O2. Oxygen is normally found as a molecule. It is called dioxygen.
How can two atoms of the same element have different masses?
Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.
Is oxygen atom neutral or charged?
Organic Chemistry
The oxygen atom is slightly negatively charged, and the carbon and hydrogen atoms are slightly positively charged.
Does everything consist of atoms?
Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons.
Does oxygen have 8 or 10 electrons?
Oxygen has atomic number eight. This means that the nuclei of all oxygen atoms have eight protons. A neutral oxygen atom will also have eight electrons. In an oxygen ion with a 2− charge, the number of protons is still 8, but the number of electrons is 10.
Do atoms have different masses?
All atoms of a chemical element have the same atomic number (number of protons in the nucleus) but may have different mass numbers (from having different numbers of neutrons in the nucleus). Atoms of an element with the same mass number make up an isotope of the element.
What is the same for all atoms of the same element?
Atoms of the same element have the same atomic number so the number of protons (and electrons) are same. But they have same or different mass numbers (like that for isotopes). Different mass number will have different number of neutrons. Was this answer helpful?
How do you find the mass of atoms?
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
What is the mole number?

What are oxygen atoms?
At standard temperature and pressure, oxygen is found as a gas consisting of two oxygen atoms, chemical formula O2.
Why does oxygen have 2 atoms?
The O2 Lewis structure has a double bond between two oxygen atoms. According to the octet rule, oxygen atoms need to bond twice. The O2 molecule is diatomic, meaning that two atoms of the same element are connected in a pair.
Can a single oxygen atom exist?
But one oxygen atom cant exist on its own, because its unstable. Usually any atom needs 8 electrons in its outer orbit in order to stay stable. But, the Oxygen atom has 6 electrons in its outer orbit.
Are all protons same?
All protons are identical. For example, hydrogen protons are exactly the same as protons of helium and all other elements, or pure substances. However, atoms of different elements have different numbers of protons.
Is every neutron the same?
Review: Neutrons are all identical to each other, just as protons are. Atoms of a particular element must have the same number of protons but can have different numbers of neutrons.
Do all protons and neutrons have the same mass?
Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well.
Is oxygen made of atoms?
Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature. A rotating model of an oxygen molecule.
Why is oxygen called O2?
The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
What is a single oxygen atom called?
This answer is not useful. Show activity on this post. O is a singular oxygen atom. O2 is a molecule made of two oxygen molecules.
Why do all atoms of an element have the same atomic number although they have different mass number?
Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
How many atomic masses does oxygen have?
What part of the atom consist most of its mass?
The nucleus is the positively charged centre of an atom and contains most of its mass. It is composed of protons, which have a positive charge, and neutrons, which have no charge. Protons, neutrons, and the electrons surrounding them are long-lived particles present in all ordinary, naturally occurring atoms.
How is the oxygen arrangement of atoms?
What is the electron arrangement of oxygen? Oxygen has eight electrons. The first two electrons will go in the n=1 level. Two is the maximum number of electrons for the level so the other electrons will have to go in a higher energy level.
What is the only element that has no neutrons?
There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons.
How many neutrons does oxygen atom have?
Which atom contains exactly 16 neutrons?
Explanation: if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.
Why do all atoms have different masses?
This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon both the number of protons and upon the number of neutrons present in the nucleus (remember that the mass of an electron is so small that it is simply ignored for the purpose of establishing the atomic mass).
