What is a possible set of quantum numbers for the last electron added to complete an atom of gallium, Ga, in its ground state?

There aren’t a lot of people who are familiar with this element. This is a type of metal that is blue and silvery in color, especially when they are at standard temperature. If in case it would be in liquid form, its color will also change. It will become white and silvery.

This type of metal will not be able to take in too much pressure. This is usually mixed with other alloys to create different items such as transistors. This can also take the form of Gallium Arsenide, which is used to generate laser light that may come from electricity.
