HBr(aq) and Ca(OH)2(aq) Express your answer as a balanced chemical equation. Identify all of the phases in your answer.

Acertain atom has 22 protons and 19 electrons. this atom loses an electron. the net charge on the atom is now 4+1+01-4-. if this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be 3+2+02-3-.
