Question

Explain the valency of an element considering sodium chloride as an example​

Answer 1

The chemical formula of sodium chloride is NaCl . Note: Note that the compounds do not have a valency. Thus sodium chloride NaCl does not exhibit a valency. But we can determine the valencies of the sodium and chlorine atom, it is 1 for both.

Answer 2

→Answer is :

For inst.ance, consider the compound NaCl. W.e know that the valency of sodium (Na) is +1 and Chlorine (Cl) is -1.

→Explanation :

Both sodium and chlorine have to gain one electron and l.ose one electron respectively to achieve stable outermost orbit. .

→Additional :

Therefore, sodium donates an electron and chlorine ac.cept the same electron.
