Question

what is the valency of carbon in co2

Answer 1

Answer:

CO2 is carbon dioxide which has carbon and oxygen in 1:2 ratio.

In the electron dot structure of the elements carbon shares two pairs of its electrons with oxygen.

Thus, it completes its octet rule and becomes stable.

Carbon requires only 4 electrons to become stable, and oxygen needs 2 electrons.

So, the valency of carbon in CO2 is 4.
