how is the reactivity of a metal summarized in the activity series? how does the placement of a metal in the activity series allow you to predict whether a reaction will, or will not, occur?

it is stable as it is in group 0 which have full outer shells of electrons

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.
