Question

17. Using graphical method deduce equations of motion​

Answer 1

Valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules. Carbon has four valence electrons and here a valence of carbon is four.

Electronic configuration of carbon (C = 6) = 1s2 2s2 2p2 = [He]  2s2 2p2

The valency of Carbon depends on the following factors:

To complete the octet structure, either carbon gains four electrons or lose four electrons.

However, if Carbon gains electrons then it would be hard for the nucleus to hold four additional electrons as carbon atom is very small in size.

If Carbon losses its electrons then it required a large amount of energ

Carbon makes four covalent bonds and attains the noblezzbzbz gas configuration by sharing it’s valence electrons.
