May 08,2020 The chemistry of an atom arises from its electrons 41#0183;The potential of an atom of an element to react with another atom arises from the need to have stable electronic configuration.Hence the electron/ s in outermost shell decides that combining capacity of a particular element.The number of electroWhat makes an atom an atom? Naked Science ForumThe point is that the properties of atoms that we are aware of on a day to day basis (chemistry)are those of the outer shells of electrons and nothing else.The atomic nucleus has no effect other than to define the number of electrons that make the atom neutral which is its normal state.What Determines an Atom's Reactivity?Apr 03,2020 The chemistry of an atom arises from its electrons 41#0183;An atom's reactivity is determined by the number of electrons in its outermost shell.Because the outer shell can hold up to eight electrons and not all elements are able to fill these shells to capacity,the fullness of the shells will determine the volatility of the atom's reactive properties as a result of the number of electrons required to complete the shell.
