Question

What is valency? How to find valency of an element? please answer me fast.... no irrelevant answers please..... ​

Answer 1

Explanation:

Valency is defined as the combining capacity of an atom or a molecule. ... If the number of electrons in the outer shell is between one to four, the compound is said to have positive valency. For compounds with electrons four, five, six, or seven, the valency is determined by subtracting the electron from eight.

Answer 2

Answer:

An element's valency is determined by the number of electrons in its outer shell. Hence, the number of valence electrons obtained from the electronic configuration of the element gives the valency i.e. the number of electrons lost, gained or shared by the element to attain the noble gas configuration.
