Elements of group 13

B-Boron = [He]2s22p1

Al-Aluminium = [Ne]3s23p1

Ga-Gallium = [Ar]3d104s24p1

In-Indium = [Kr]4d105s25p1

Tl-Thallium = [Xe]4f145d106s26p1

Abundance and Occurrence of 

group 13 elements

Aluminum is the most abundant metal known and third most abundant element by mass in the earth’s crust.

Boron is a rare element and occurs as concentrated deposits of Borax, Kernite . 

Gallium is twice as abundant but indium and thallium are less common.
