Question

which metal react fastly with water

Answer 1

This page looks at the reactions of the Group 1 elements - lithium, sodium, potassium, rubidium and caesium - with water. It uses these reactions to explore the trend in reactivity in Group 1.

The Facts

General

All of these metals react vigorously or even explosively with cold water. In each case, a solution of the metal hydroxide is produced together with hydrogen gas.

This equation applies to any of these metals and water - just replace the X by the symbol you want.

In each of the following descriptions, I am assuming a very small bit of the metal is dropped into water in a fairly large container.

Answer 2

Answer:

sodium (Na):-

vigorous reaction with cold water

calcium (Ca):-

less vigorous reaction with cold water

magnesium (Mg):-

slow reaction with cold water, vigorous with hot water
