Question

what would be the most likelycharge of an ion formed from an atom with the electron configuration 1s^22s^2p^4:
a) +1
b) -1
c) +2
d) -2

Answer 1

probably it is option D

because to get its shell completely filled the atom accepts 2 electrons and therefore its charge will be -2

and the above configuration is of OXYGEN atom

hope it helps you
