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).
The vertical columns are known as groups.
The horizontal rows are known as periods.
A group is all the elements in the same column. They all share the same chemical properties because they all have the same valence electron structure.
The vertical columns are called groups and the horizontal row of elements are called period on a periodic table.
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 family is a column of elements a period is a row of elements
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
Aluminum has its electrons in three different energy levels. Therefore it is in third period. As it has three valence electrons, it is located in group 3.Aluminium is found in group-13. Its period umber is 3. Its atomic number is 13.Aluminium is a metal element. It is in the 13th group of the periodic table. And it belongs to the 3rd period.
The elements on the left (well, pretty much the whole table bar the far right side) are metals.

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.
Group or family
These elements are called halogens.
They are groups
The term used is group. It is also called family.
The meaning is that chemical properties are periodically repeated in the table.
a family is a column of elements a period is a row of elements
The rows in periodic table are known as periods. The arrangement is such that elements with similar properties fall in the same period.
