Reactivity in a group of metals
WebThe elements in Group IIIA (B, Al, Ga, In, and Tl) can be divided into three classes. Boron is the only element in this group that is not a metal. It behaves like a semimetal or even a nonmetal. Aluminum is the third most abundant element in the earth's crust. It is just slightly less reactive than the active metals.

Group 1 is the most reactive group of metals. The Group 1 metals get more reactive the lower they are in the group. Group 2 metals are also reactive. Questions WebFour major factors affect reactivity of metals: nuclear charge, atomic radius, shielding effect and sublevel arrangement (of electrons). Metal reactivity relates to ability to lose electrons (oxidize), form basic hydroxides, form ionic compounds with non-metals. In general, the bigger the atom, the greater the ability to lose electrons.
