Boron Group- Group 13-Periodic Table

Boron Group–The boron group are the elements found in group 13 of the periodic table. The Boron group includes the following elements.

Boron (B)

Aluminum (Al) 

Gallium (Ga)

Indium (In)

Thallium (Tl)

Nihonium (Nh)

The elements of the Boron group are post transition metals except for Boron which is a metalloid, and Nihonium which is a synthetic chemical elementand extremely radioactive. 

All of the elements of the boron group have three valence electrons. The elements in the boron group, except for boron, are soft. They are relatively reactive at moderate temperatures, except boron is reactive at very high temperatures.

The metals in the group are good conductors of heat and electricity except for boron. As you move down the boron group the boiling point gets lower and the density increases.

Aluminium is a popular boron group element and is found in the earth’s crust. Gallium is found in nature and Indium is fairly abundant in the earth’s crust. Thallium is found in small amounts throughout the planet. Boron is not found naturally on earth.
