Question

The number of valence electron/s present in the alkali metals is/are:

• A. 1
• B. 7
• C. 4
• D. 2

Answer 1

The correct option is A 1

Valence electrons are the electrons which occupy the outermost shell of an atom. These electrons participate in the formation of chemical bonds with other atoms. The elements of group 1 of the periodic table are called the alkali metals. All the alkali metals have a single electron in the outermost shell. Thus alkali metals have one valence electron.
