A neutral nitrogen atom has 7 electrons, 7 protons, and 7 neutrons. What is its total charge? If we remove 2 of the electrons, now what is its charge? what is its charge if we add 2 electrons to the neutrol atom instead? give charge in Coloumbs.

neutral atom q=0;
if you remove 2 electrons:
q= +2•1.6•10⁻¹⁹= +3.2•10⁻¹⁹ C
if you add to electrons:
q= - 2•1.6•10⁻¹⁹= - 3.2•10⁻¹⁹ C
