Question

Write the corresponding electron configuration for the pictorial representation. The electron configuration is 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 1 3 d 10. Give the full electron configuration. Do not use the noble gas abbreviation.

Answer 1

Answer:

The electronic configuration is

1s² < 2s² < 2p⁶ < 3s² < 3p⁶ < 4s¹ < 3d¹⁰

Explanation:

The energy of the main shell depends on principal quantum number and energy of subshell depends on the summation of principal and azimuthal quantum number.

Lower (n + l) value says lower energy of the subshell and higher (n + l) value represent higher energy of the subshell.
