Q. 8.Give the electronic configuration of 02- and Na+ ions. Are they isoelectronic? |
|
Answer» (b) Na+ ion The electronic configuration of Na atom is 1s2 2s2 2p6 3s1. A positive charge on the species indicates the loss of an electron by it.∴ Electronic configuration of Na+ = 1s2 2s2 2p 6 3s0 or 1s2 2s2 2p6 (c) O2- ion The electronic configuration of 0 atom is 1s2 2s2 2p4. A dinegative charge on the species indicates that two electrons are gained by it. |
