How many valence electrons do the elements of alkali metals have?

Answer 1

Valence electrons are the electrons present in the outermost shell of an atom.

You can easily determine the number of valence electrons an atom can have by looking at its Group in the Periodic Table.

For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.

Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively.

Answer 2

The alkali metals have one valence electron.

Answer 3

The alkali metals in group 1 of the periodic table all have 1 valence electron. This makes them highly reactive as they tend to lose their outer electron to achieve a stable electron configuration.
