Question

define valency by taking example of silicon ​

Answer 1

Explanation:

The valency is equal to the number of electrons in the outermost shell (valence shell) of an atom. For example, silicon (atomic number 14) has the following electronic distribution: K = 2, L = 8, M = 4. In the outermost shell there are 4 electrons so, the valency of silicon is 4.
