More unstable an electron configuration , the more reactive an atom will become.
How electron configuration influences the chemical behavior of an atom?
This is happen generally, If we look at the Group 1 elements in the periodic table, they are all highly reactive as they have 1 electron in their outermost shells - an unstable configuration in terms of energy.
Also, the noble gases in Group 8 in the periodic table are 'inert' that means they don't react (or more correctly, have an incredibly low reactivity). This is because they have 8 electrons in their outermost shell and thus have no need to acquire or lose electrons to possess a stable electron configuration.
Hence, electron configuration influences the chemical behavior of an atom.
