The element with a completely filled p-subshell is:
1 answer:
The element with the completely filled p-subshell is Ar (Option C)
<h3>What is electronic configuration?</h3>This is the arrangement of elecartons in the atomic orbitals of an element. The modern electronic configuration makes use of the s, p, d, f orbital notation where
- Sharp (s) = Maximum of 2 electrons
- Principal (p) = Maximum of 6 electrons
- Diffuse (d) = Maximum of 10 electrons
- Fundamental (f) = Maximum of 14 electrons
To obtain the correct answer, we shall write the electronic configuration of each element given in the question. This is illustrated below
- Na (11) => 1s² 2s²2p⁶ 3s¹
- P (15) => 1s² 2s²2p⁶ 3s²3p³
- Ar (18) => 1s² 2s²2p⁶ 3s²3p⁶
- Al (12) => 1s² 2s²2p⁶ 3s²
From the above illustrations, we can see that only Ar has completely filled p-subshell.
Thus, Ar (Option C ) is the correct answer to the question
