Question

.the third shell of an atom 'x' has six electrons. a) write the subshell electronic configuration of "x". 1 b)what will be the normal valency of 'x'?​

Answer 1

Answer:

a) The subshell EC is 2, 8, 6.

b) The normal valency of x is 2.

Explanation:

• The first shell, i.e. K-shell can accommodate only 2 electrons.
• The second shell, i.e. L-shell can accommodate a maximum of 8 electrons.
• It is given that the third shell, i.e. M-shell has 6 electrons.
• Therefore, the subshell electronic configuration of the atom x will be 2, 8, 6.
• The third shell requires 2 more electrons to complete its octet.
• Therefore, the normal valency of the atom x is 2.
