Numbers and arrangements of electrons in their outermost shells.
The number of protons
The groups in the periodic table tell you what each element within them will react with, the number of valance electrons the element has, and what family it is in.
Each vertical column in the periodic table is group.There are 18 groups in periodic table.Seventeenth group belongs to halogens.
Each column going down the periodic table is an atomic group.
Periodic means reoccuring. On the periodic table, periodic refers to the elements in each group having some of the same simularities and some of the same properties.
A vertical column on the Periodic table on the periodic table is called group. There are 18 groups on the table. These groups are also referred to as families. Each element in a group has the same number of valence electrons and, therefore, similar chemical properties (there are some exceptions though).

elements in a group have the same number of valence electrons
Each group has a group number.
On the periodic table, the family nitrogen belongs to is Group Vb. In their outer electronic shell, each of the elements within this group have five electrons.
Each row of the periodic table gives you one full electron shell, then you start a new shell when you start a new row. In each group you have the same number of electrons in the outer shell, you just get more shells as you go down the table.

They are the vertical columns on the Periodic Table. Each column (top to bottom) is considered to be a group or family.
A group, there ae 18 of them.
what property does each of the elements have
Each column is a group of chemical elements.
