How Would You Define The Periodic Table Group Names


As you know, a periodic table is a tabular arrangement of elements into groups and periods. There are different Periodic Table Group Names given to each group or family of elements.

Groups are the horizontal columns which are 18 in number. They are arranged in a manner in which all the elements in a group are said to belong to the same group or family. Also as we go from top to bottom in a periodic table, the valency of the elements increases.

Since each group has similar properties, all the group can be categorized into families. For example, the first group is said to belong to the lithium family

Periodic Table Groups and Periods

A group in a periodic table is the horizontal column from top to bottom across a periodic table. There are 7 groups across a periodic table. Each group has elements which have similar chemical properties and thus belong to the same family of elements. For example, the first group is of the lithium family, and the second group is of Berillium group.

The rule followed by the elements across a group is that the valency of the elements increase as one goes from top to bottom across a periodic table.

A period is a vertical row across a periodic table. All the elements across a period have the same number of electron orbitals. A rule followed by the elements of a group is that the metallic property of an element decreases as one goes from left to right across a period. And like a group, the valency of element increases as one goes from left to right across a period.
