This appears to be the formula for the oxide ion. Since oxygen has 8 protons, and this ion has a 2- charge, it must have 10 electrons.

O2- has 10 electrons. Each oxygen atom contributes 8 electrons, and since there are two oxygen atoms in O2-, the total number of electrons is 16. The charge of -2 indicates that 2 electrons have been gained, so the total number of electrons in O2- is 16 - 2 = 14.

When at atom is charged it us called an ion how many electrons are in 02?

O2 has 16 electrons. Each oxygen atom has 8 electrons, and since O2 is a molecule made of two oxygen atoms, the total number of electrons is 16.


How many electrons are in 02?

There are 16 electrons in an O2 molecule. Each oxygen atom contributes 8 electrons, so in a molecule of O2, there are a total of 16 electrons.


How many electrons do the oxygen have if they are neutral?

An atom of oxygen has 8 electrons, an O2 Molecule would therefore have 15, I think.


Does O2 have shared electrons?

Yes, O2 has shared electrons. In the O2 molecule, each oxygen atom shares two electrons with the other oxygen atom, forming a covalent bond. This sharing of electrons allows the atoms to achieve a stable electron configuration.


What is the electrons configuration for O2-?

The electron configuration for O2- is 1s2 2s2 2p6. This means that there are a total of 10 electrons, with the two additional electrons compared to neutral oxygen filling the 2p orbital.
