Group 13

The elements in Group 13 are Boron, Aluminum, Gallium, Indium, and Thallium

Group 13 has 3 valence electrons.

Boron is used as rocket fuel igniter, pyrotechnic flares, and then the Boron compounds are used in eye drops, antiseptics, washing powder, and tile glazes.

Gallium is used as a silicon substitute since it is similar to silicon so it is used in red LEDS, solar panels, phones, blue ray technology, and pressure switches.

Aluminum is the most abundant element in the earth's crust but since it is not found freely in nature you must dig for it.

Aluminum is used in most kitchen utensils, cans, foil, electrical transmission lines (aluminum is a better conductor than copper and is cheaper than copper).
