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 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 \(\text- 6 + 6 = 0\). Find the overall charge for the rest of the elements on the list.
\(\text-9.2 + 4.4\)
\(\text-81.4 + (\text-12)\)
\(51.8 + (\text-0.8)\)
