Question

element L has an electronic configuration of 2.8.3 and element M has a configuration of 2.6, what would be the formula of the compound formed between L and M

Answer 1

Required Answer:-

Element L has an electronic configuration of 2,8,3 which means it has 3 electrons in the outermost shell. To attain stability and complete octet, it can lose 3 electrons and gain +3 charge.

Element M has a configuration of 2,6 which means it need 2 more electrons to complete it's octet. So, it can gain 2 electrons and attain -2 charge.

Hence, by crisscross method the compound formed by L and N would be:

$\huge{ \boxed{ \rm{ \red{L_2M_3}}}}$
