The atomic mass of X is 12. Write its electronic configuration. Mention it's valency and also the number of valence electrons?

Open in App

Solution

Atomic mass = double of atomic number
Atomic mass = 12
so atomic number = 12/2 = 6
so element would be K= 2, L= 4, so electronic configuration = 2, 4
Outer most shell has 4 electrons, so its valency = 4
Number of valence electrons = 4
