Detailed explanation-1: -Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus.
Detailed explanation-2: -Oxygen atom has 8 electrons, 8 protons and 8 neutrons.
Detailed explanation-3: -Oxygen is group 8 element, so, the atom of oxygen has 8 protons and 8 electrons. The ion has the same number of protons because you never lose a proton to make an ion. But in the case of oxide form, it carries two negative charges. Negative charge come due to the transfer of electron.
Detailed explanation-4: -Subatomic Particles in an Ion Oxygen has the atomic number 8 so both the atom and the ion will have 8 protons. The average atomic mass of oxygen is 16.
Detailed explanation-5: -Number of electrons in oxygen atom is 8. So, the electronic configuration is 2, 6.
