Question:Which atom would be expected to have a half-filled 4ssubshell?

Short Answer

Expert verified

Potassium is expected to have a half-filled 4s subshell.

Step by step solution

01

describing the conditions to determine the required atom

We know that pairing is done after all the orbitals are partially filled. For a half-filled 6p subshell, we need to check the elements in the 6th period of the periodic table.

02

determining the atom has a half-filled 4s subshell

The atom has a half-filled 4s subshell this means that the last part is to be 4s1. So, the electron configuration will be [Ar]4s1 which is of potassium (K).
