A carbon ion has a charge of -2. If a neutral carbon atom 12 protons and 12 neutrons, how many electrons will this ion have?

hloride, what is the mass of calcium in

explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

the objects have the same charge is correct.
