How many valence electrons are available for bonding in silicon?
four
five
eight
fourteen

four

Explanation:

Silicon is the element of group 14 and third period. The atomic number of silicon is 14 and the symbol of the element is Si.

The electronic configuration of the element silicon is:-

As seen from the electronic configuration, the number of valence electrons are four which are present in the 3s and the 3p shell.

These electrons in the silicon will be available for bonding.
