Fill interior the shells as you bypass. as an occasion....if there are 12 electrons then there are 2 interior the 1st shell, 8 interior the subsequent, and then 2 interior the final, on account that there needs to be 8 electrons in each shell different than the 1st, the atom needs 6 others to alter into good. The sort of covalent bonds are based on the kind of electron necessary by way of each atom
