Group 13 (13th vertical column of the periodic table) is called the boron group and it consists of boron (B), aluminium (Al), gallium (Ga), indium (In) and thallium (Tl).
The
Boron Group - Group 13
Group 13 (13th vertical column of the periodic table) is called
the boron group and it consists of
boron (B), aluminium (Al), gallium (Ga), indium (In) and thallium (Tl) (Figure
4.1).
All elements within group 13 show a wide
variety of properties. It is important to note that boron is a metal-loid
(semi-metal) whereas aluminium is a metal but shows many chemical similarities
to boron. Aluminium, gallium, indium and thallium are considered to be metals
of the ‘poor metals’ group.
Metalloids are elements that display some properties characteristic for
metals and some characteristic for
nonmetals.
In this chapter, the general chemistry of group 13 elements is
discussed as well as some clinical applications for boron and aluminium.
Further clinical applications for boron as well as applications for thallium
can be found in the chapter on radiochemistry (Chapter 10).
