In the alkali metals group, what happens as the atomic number increases?
The metal becomes more reducing........
The metal becomes more reducing........and MUCH MORE reactive.
Lithium is fairly zippy in water; sodium is even zippier. Potassium will give you bangs and pops and flames.
The metal also reduces its melting point. Potassium has a lower melting point of
AS the atomic number increases, the valence electron becomes farther removed from, and less strongly attracted to the nuclear core; and as a result the reactivity of the metal increases.
