Periodic Table Groups Explained! (With Labeled Group Names)

Periodic Table Groups

Periodic table groups are the vertical columns on the periodic table. There are a total of 18 groups (vertical columns) on the periodic table.

  • Group 1: Alkali metals (hydrogen excluded)
  • Group 2: Alkaline earth metals
  • Group 3-11: Transition and inner transition metals group
  • Group 13: Boron group
  • Group 14: Carbon group
  • Group 15: Nitrogen group (pnictogens)
  • Group 16: Oxygen group (chalcogens)
  • Group 17: Halogen group 
  • Group 18: Noble gases

Let’s discuss each of these groups of periodic table one by one.

Group 1: Alkali metals

Alkali metals

Alkali metals are the group 1 elements present on the periodic table. Hydrogen is not included in the alkali metals group because it is classified as a nonmetal.

The list of alkali metals with its atomic number and symbol is mentioned below.

11NaSodium
19KPotassium
37RbRubidium
55CsCesium
87FrFrancium

Group 2: Alkaline earth metals

Alkaline earth metals

Alkaline earth metals are the group 2 elements present on the periodic table.

The list of alkaline earth metals with its atomic number and symbol is mentioned below.

Atomic numberSymbolName of element
4BeBeryllium
12MgMagnesium
20CaCalcium
38SrStrontium
56BaBarium
88RaRadium

Group 3-11: Transition and Inner transition metals group

Transition and Inner transition metals group

Transition metals and Inner transition metals are the elements that are lying from group 3 to group 11.

The elements lying in the two rows which are lying at the bottom of the periodic table are the inner transition metals.

These elements are the part of transition metals only, but they have different properties. So they are placed separately at the bottom of the periodic table.

These two rows of inner transition elements are known as lanthanides and actinides.

Group 13: Boron group

Boron group

Boron group includes the group 13 elements present on the periodic table.

50SnTin
82PbLead
114FlFlerovium

Group 15: Nitrogen group (pnictogens)

Nitrogen group (pnictogens)

Nitrogen group (also known as pnictogens) includes the group 15 elements present on the periodic table.
