Question

Atomic number of chlorine is 17 and mass number is 35. Draw the structure of chlorine showing the

composition of

the nucleus as well as distribution of electron in different shells. Also comments on its valence.​

Answer 1

Valency is defined as the combining capacity of atoms or molecules. It is obtained from the number of electrons present in the outermost shell of an atom. The atomic number of chlorine is 17 and the electronic configuration is 2, 8, 7. Therefore, the valency of chlorine is 1
