Since Oxygen's atomic number is 8, it has 8 protons. However, the atomic
number is a not always indicative of how many electrons an atom has, but ...
All atoms have at least one proton in their core, and the number of protons
determines which kind of element an atom is. For example, an oxygen atom has
In one atom of oxygen? 8 protons. By definition, always, and forever. In one
molecule of oxygen gas, which is O2? 2 times 8 = 16 protons. Always ...
How is a hydrogen atom different from an oxygen atom? To answer these ...
Atomic number of an atom is the number of protons present in it. A periodic table
Jan 13, 2013 ... The atomic mass is the sum of the number of protons (2) and the number of
neutrons (2). ... This oxygen atom has 8 electrons in two shells.
Different versions of the same element are called isotopes. Below are isotopes of
oxygen, they all have the same number of protons but different numbers of ...
Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic
number of an element never changes, meaning that the number of protons in the
