Question

The alkali metals all react vigorously with water. Which alkali metal would react to the greatest extent if you have equal amounts of each?

Answer 1

Explanation:

RUBIDIUM(rb)

since all alkali metals reactivity increases down the group as atom becomes more eager to lose is an electron in valence shell

Answer 2

Alkali metal which would react with water to the greatest extent if you have equal amounts of each is :

• Reaction of alkali metal with water :

2M(s) + 2H2O(l) ⟶ 2M+(aq) + 2OH−(aq) + H2(g)

where M = Li, Na, K, Rb, Cs, Fr

• All alkali metal are very reactive with water, some even gets explode when come in contact with water.

•Down the group electron giving tendency increases, therefore metal's reducing property also increases.

• Hence, Fr is most reactive alkali metal with water among all other.
