Bohr's model of the atom explains the reactivity of group 1 metals, as it applies the rule that electrons are in fixed orbits, and that the shells fill up from the centre. If each shell is full it can't take any more electrons so for an electron to migrate into an already full shell another electron must take its place. This means that there will always be one electron on the outside until it undergoes ionic bonding with a non-metal and becomes a stable positive ion.

How does the chemical reactivity to alkali metal vary?

As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.

Would a metal in the boron family or alkali metal be more reactive?

A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.
