There are total 18 different groups in Periodic table. Group 1: Alkali metals group (hydrogen not included) Group 2: Alkaline earth metals group. Group 3-12: Transition and Inner transition metals group. Group 13: Boron group. Group 14: Carbon group. Group 15: Nitrogen group. Group 16: Oxygen group. Group 17: Halogen group.
Periods, groups, and families of the periodic table defined with a labeled diagram. How many are there. What are their names. Learn their properties with examples.
Modern group names are numbers 1–18, with the 14 f-block columns remaining unnumbered (together making the 32 columns in the periodic table). Also, trivial names (like halogens) are common. In history, several sets of group names have been used, based on Roman numberings I–VIII, and "A" and "B" suffixes. [2][3] v. t.
A group is a vertical column down the periodic table, while a period is a horizontal row across the table. Both groups and periods reflect the organization of electrons in atoms. Element atomic number increases as you move down a group from top to bottom or across a period from left to right.
Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.

An element group is a column of elements on the periodic table. There are 18 element groups, which appear on the periodic table as numbers listed above the element columns. For example, the first column is group 1, I, or IA, depending on the numbering system.
Classification of elements into groups. The six noble gases—helium, neon, argon, krypton, xenon, and radon—occur at the ends of the six completed periods and constitute the Group 18 (0) group of the periodic system. It is customary to refer to horizontal series of elements in the table as periods and vertical series as groups.
