What is the electron configuration of the gallium ion?
Gallium, Ga has 31 protons and 31 electrons. The superscripts represent the electrons present in each region of the periodic table.
The sum of these superscripts should equal the atomic number for a neutral atom. The last electron is in the 4th period, in the p region and the first electron in that region.
The most common electron configuration for the gallium ion,
Gallium is in Group 13. It has 31 electrons.
Its electron configuration is
We form cations by removing electrons first from the outermost
The options for
#4p#electron and form #"Ga"^+#
#4p#electron and both #4s#electrons and form #"Ga"^(3+)#.
By far the most common ion of Group 13 metals is +3.
So. the most common gallium ion is
