Group of boron
as group of boron one designates the chemical elements of the 13. Group of the periodic system. In former times the group was called also group of earth metals, what was however confusing, since boron ranks among the metalloids.
The elements of the group are boron, aluminum, gallium, Indium and thallium. Not all elements of this group are metals , boron are actually a nonmetal and as earth metal are not designated, therefore also the new name group of boron. The elements of this group occur in the earth's crust relatively frequently as oxides. The name thatGroup is derived from the alumina (alumina). The designation ground connection was taken over for the remaining metallic oxides.
