What happens to the reacivity of the alkali metals as you go down the group?

Answer 1

the reactivity in presence of heat or another reactive element increases down the group due to increase in atomic size but in water reactivity decrease down the group due to decrease in charge density ,the smaller ion forms strong bonds with water molecules.

Answer 2

Yes. As atomic size increases, the sole valence electron in an alkali metal atom is released more easily, because, in simplified terms, this outer electron is farther from the positive charge of the nucleus and the attraction of the nucleus is partially overcome by repulsions from the electrons in the internal shells of the atom. There is one more such shell with each step down the periodic table in the alkali metals group.

Answer 3

As you go down the group the metals become moreand more reactive,

Answer 4

The reactivity with water increase down in the group.

Answer 5

It increases; i.e. becomes more alkaline
