1)
Number of electron in O = 8
Electronic configuration is 1s2 2s2 2p4
Since charge on O is +2
So, we need to remove 2 electrons
Electrons are always removed from highest number orbital
Removing 2 electron from 2p
Final electronic configuration is : 1s2 2s2 2p2
Answer: 1s2 2s2 2p2
2)
Number of electrons in O2+ = 6
Atomic number is 6 for C
So, this is isoelectronic with Carbon
Answer: Carbon
