how to find valency of an atom

Answers

Answered by Sainty7973

The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.

harish1322: in which class you read

aswinsajay616: hmm so, if the shell is full the valency = 0 and if its not full the other shell's electrons will be the valency

harish1322: valency is 0

aswinsajay616: am i right?

harish1322: yes

aswinsajay616: finally :3 i learnt Valency

aswinsajay616: anyways i gotta go for lunch

harish1322: ok

aswinsajay616: if need ill message you

aswinsajay616: now bye
