Write electronic configuration of hydride ion and oxide ion​

Answer» ER:

For EXAMPLE, we know that Oxygen always forms 2- ions when it makes an ION. This would add 2 ELECTRONS to its normal configuration making the new configuration: O2- 1s22s22p6. With 10 electrons you should note that oxygen's electron configuration is now exactly the same as Neon's.
