Question

what is the valency of lithium,flourine and sodium?​

Answer 1

Explanation:

For example, all the metals, be it hydrogen, lithium, sodium and so on, present in column 1 have valency +1. Similarly, all the elements present in column 17 have valency -1 such as fluorine, chlorine, and so on.

Answer 2

Explanation:

• For example, all the metals, be it hydrogen, lithium, sodium and so on, present in column 1 have valency +1. Similarly, all the elements present in column 17 have valency -1 such as fluorine, chlorine, and so on.

• The valency of chlorine is 1. Hint: valency of a sodium atom is +1 and chlorine is −1 . sodium donates its outermost electron and chlorine atom gains the same electron to complete its octet.
