Question

Define valency?write down the valency of Carbon?

Answer 1

Answer:

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)

Answer 2

$\huge{\boxed{\mathfrak{\red{Answer}}}}$

$\huge{\underline{\sf{\pink{Valency}}}}$

Valency is defined as combining power of an element with other atom to form chemical bond.

Valency refers to electron in outer shell of an atom.

Example: Na(2,8,1) Valency of Na is 1

.

Cl(2,8,7) Valency of Cl is 1. Chlorine is short of one electron to complete its octet.

$\huge{\underline{\sf{\purple{Valency\:of\:Carbon}}}}$

Valency of carbon is 4.Thus, it has 4 valence electrons. It shares these 4 valence electrons to form 4 covalent bonds.
