Question

Define valency by taking examples of silicon and oxygen. Brainly

Answer 1

Valency is bonding tendecyof any atoms .that is those atom attached how many atoms .

In generally oxygen atoms having two valancy.

And silicon atom have 4 valency like carbon .because that atoms having 2and 4 valence electrons so it's form generally 2 and 4 bond with respective atoms.

Answer 2

First the electronic configuration of silicon is2,8,4

The valency is 4

O= 2,6

The valency is 3.

The electrons present in outermost shell.
