Often asked: What Are The 9 Families In The Periodic Table?

9 Element Families

  • Alkali Metals: Group 1 (IA) – 1 valence electron.
  • Alkaline Earth Metals: Group 2 (IIA) – 2 valence electrons.
  • Transition Metals: Groups 3-12 – d and f block metals have 2 valence electrons.
  • Boron Group or Earth Metals: Group 13 (IIIA) – 3 valence electrons.

What are the families of the periodic table?

Families of the Periodic Table. On the periodic table, there are families which are groups of elements with similar properties. These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases.

How many families of the periodic table are there?

In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered.

What are the 10 groups of the periodic table?

Terms in this set (10)

  • Alkali metals. Alkali metals Group 1: very reactive metals which do not occur freely in nature.
  • Alkaline Earth Metals. Group 2: next reactive metals, found in earths crust but not in elemental form.
  • Transition Elements.
  • Lanthanides and Actinides.
  • Boron Group.
  • Carbon Group.
  • Nitrogen Group.
  • Oxygen Group.

What family is Group 18?

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the “inert gases” due to the fact that their filled valence shells (octets) make them extremely nonreactive. The noble gases were characterized relatively late compared to other element groups.

  • Halogens.
  • Noble gases.

What are the 18 groups in periodic table?

Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
