∙ 7y agoThere are 2 electrons in an oxygen ion with a charge of -2. This is because oxygen normally has 6 electrons, but when it gains 2 extra electrons to become an ion with a charge of -2, it now has 8 electrons total.
There are 16 electrons in an O2 molecule. Each oxygen atom contributes 8 electrons, totaling 16 electrons in the molecule.
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.
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.
Beryllium (Be) has 4 electrons.
Xenon has 54 electrons.
