Question

The valence electron configurations of several atoms are shown. How many bonds can each atom make without hybridization?

A) Si 3s23p2

B) C 2s22p2

C) S 3s23p4

Answer 1

In A] the Si 3s23p2 it has one lone pair and 2 unpaired electrons hence it can make 2 bond

In B] the C 2s22p2 it has one lone pair and 2 unpaired electrons hence it can make 2 bond

In cC the S 3s23p4; Here we have 2 unpaired electrons and 2 lone pair and hence it can form 2 bond

Valance electron:

The electrons which are present in the outer most energy level are known as valance electron. This can be calculated by the group number of the element. Generally the group number is same as the valance electrons of any elements.

Electron configuration:

The arrangement of electrons in an atom by a superscript, in each sublevel is known as electron configuration.
