Answer: Option (d) is the correct answer.
Explanation:
The atomic number of Al is 13, so the electronic configuration of is as follows.
=
= [Ne]
The atomic number of Sc is 21, so the electronic configuration of is as follows.
=
= [Ar]
The atomic number of As is 33, so the electronic configuration of is as follows.
=
= = [Kr]
The atomic number of Ga is 31, so the electronic configuration of is as follows.
=
=
Therefore, we can conclude that galium (Ga) ion does not have a noble gas configuration in its ground state.
