Question

2.The ‘d’subshell of an element with 4 shells is completely filled and there are two electrons in the fourth shell. a) How many electrons can be accomodated in ‘d’subshell? b)Write the subshell electronic configuration of the element?


​

Answer 1

Answer:

the capacity of d shell is to accommodate 18 electrons

Answer 2

heye, buddy !!

a) if two electrons are filled in the 's' subshell of the first shell, the resulting notation is '1s2'. With the help of these subshell labels, the electron configuration of magnesium (atomic number 12) can be written as 1s^2 2s^2 2p^6 3s^2.

b) 10 electrons

The third shell has three subshells, labeled s, p, and d. The d subshell can hold a maximum of 10 electrons.

cheers !
