I believe it is Metals. If I may be wrong, please improve...
The most useful property of metalloids is their
Metals

There are 18 main groups in the modern periodic table of elements.
The first two groups--alkali metals and the alkali earth metals--are the most reactive.
18
Group 18, also called the noble gases, contains the elements that are nonreactive.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
Groups 3-12 have elements with the most diverse set of properties in the periodic table. They are transition elements.

This is the group 18 of the periodic table of Mendeleev.
Group 18, also called the noble gases, contains the elements that are nonreactive.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
There are three types of elements: metals, metalloids, and nonmetals. Most elements are metals.
Groups 15, 16 and 17.
There are total 18 groups in the periodic table that contains elements having same properties.
