- The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)arrow_forward.Which of the following substances would be considered basic?
