One of the particles in an atom is called an electron. It has a charge of -1. Another particle in an atom is a proton. It has a charge of +1. the charge of an atom is the sum of the charges of the electrons and the protons. A carbon atom has an overall charge of 0 because it has 6 electrons and 6 protons and -6 + 6 = 0. Find the overall charge for the rest of the elements on the list.

charge from electrons charge from protons overall charge
carbon -6 +6 0
neon -10 +10
oxide -10 +8
copper -27 +29
tin -50 +50

there are suppose to be 4 answers thanks!!
