Group 18 on the Periodic Table contains the Inert Gases. Inert Gases tend to be unreactive. This group has the elements Helium, Neon, Argon, Krypton, Xenon, and Radon.
inert gases; noble gases
the noble gases.
chemistry
they represent elements. the elements in a given column (or group) have the same number of valence electrons and hence similar properties.
groups or family:))
hydrogen
All elements within a column are called a group.
sorry I don't know
chemistry
Elements in a given column have the same number of valence electrons and hence the similar properties.

A group is a column in the periodic table of elements.
a family is a column of elements a period is a row of elements
Representative elements
This is probably a reference to the periodic table of the elements, which has columns. All the elements in a given column have the same configuration of valance electrons. There is a column of noble gases, a column of halogens, etc.
The elements in a column on the periodic table form a group (or family) because they have similar physical and chemical properties.
the elements in a given column have the same number of electrons in their outermost shell and hence have similar chemical properties.
groups
A column of elements in the periodic table is called a group or
