Question

Atoms contain charged particles called protons and electrons. Each proton has a charge of +1, and each electron has a charge of –1. A sulfur ion has 16 protons and 18 electrons. Find the net charge.

Answer 1

As question says 16 proton with +2 charge gives us 16.(+1)=+16 charge
and 18 electron with (-1) charge gives us 18.(-1)=-18 charge
16-18=-2 net charge
