Question

This diagram is a model of the nitrogen atom.

How many electrons, protons, and neutrons are in this atom, and how many additional electrons are needed to completely fill the outer shell of this atom? Protons are orange.



A.
7 electrons, 8 protons, 7 neutrons; 1 additional electron is needed to completely fill the outer shell of this atom

B.
7 electrons, 7 protons, 8 neutrons; 1 additional electron is needed to completely fill the outer shell of this atom

C.
7 electrons, 7 protons, 8 neutrons; 3 additional electrons are needed to completely fill the outer shell of this atom

D.
7 electrons, 8 protons, 7 neutrons; 3 additional electrons are needed to completely fill the outer shell of this atom

Answer 1

C.
Nitrogen has the atomic no. of 7 so the proton and the electron no. is 7.
Three more electrons are needed to fulfil the octet structure: 2,8
