Question

If an atom has 7 protons, 8 neutrons, and 10 electrons, then it has a net charge of . On the other hand, if an atom has 3 protons, 3 neutrons, and 2 electrons, its net charge is .

Answer 1

Answer:

Neutrons play no role in the net charge of an atom, so you can ignore them here.

Proton = 7

Electron = 10

Net Charge = 7 - 10

= -3

Again,

Proton = 3

Electron = 2

Net Charge = 3 - 2

= 1
