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.
chemistry
they represent elements. the elements in a given column (or group) have the same number of valence electrons and hence similar properties.
hydrogen
groups or family:))
A vertical column is called a 'group.' A horizontal row is called a 'period,' thus the periodic table.
sorry I don't know
chemistry
Elements in a given column have the same number of valence electrons and hence the similar properties.

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 given column have the same number of electrons in their outermost shell and hence have similar chemical properties.
groups
The elements that are listed in vertical columns all share specific aspects. These aspects include having the same number of valence electrons and having similar chemical properties.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
A group of elements.
iDkkk Lmaoo !!
