Write the electronic configuration of 1.H- 2.Na+ 3.O^2- 4.F-

1.	Write the electronic configuration of 1.H- 2.Na+ 3.O^2- 4.F-
Answer» ONG>ANSWER: $\implies{\sf H^{-} \: = \: 1s^2}$ $\implies{\sf Na^+ \: = [Ne] \: 3s^1}$ $\implies{\sf O^{-2} \: = [He] \: 2s^2 \: 2p^4}$ $\implies{\sf F^- \: = [He] \: 2s^2 \: 2p^5}$

Answer» ONG>ANSWER:

$\implies{\sf H^{-} \: = \: 1s^2}$
