Question

if the protons , electrons and neutrons is 9 then what is the electronic configuration .
also please explain how to find the electronic configuration​

Answer 1

Answer:

The answer is in the attachment above.

Answer 2

Answer:

Protons=9, Electrons=9

Electronic Configuration=2 in the 1st shell(maximum) 8 in the second shell(maximum)

Explanation:

There are 9 electrons and protons. So its electronic configuration=2 in the first shell and 7 in the second shell. To attain the stable electronic configuration, it needs 1 more electron to become maximum 8....So the valency is +1(+1 means it needs one more electron to attain the electronic configuration).
