Question

Define the valency of an element​

Answer 1

Answer:

Valency can be defined as the combining capacity of an element. The electrons present in the outermost most shell of an atom are known as valence electrons and they determine the valency. The valence electrons take part in chemical reaction and they determine the chemical properties of the elements. Let us take an example,                                                                        The atomic number of carbon is 6                                                                        Its configuration is =2,4 It means valency of carbon is 4.

Explanation:

Answer 2

In chemistry, the valence or valency of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules.
