Question

the group of element in periodic table indicates ​

Answer 1

The group of elements in the periodic table indicates the number of valence electrons.

• In chemistry, a group (also known as a family) is a column of elements in a periodic table of chemical elements.
• There are 18 numbered groups in the periodic table; f-block columns (between groups 2 and 3) were not numbered.
• The elements in a group have the same physical or chemical properties as the outer electron shells of their atoms (i.e., the same basic charge) because many chemical elements are governed by the orbital position of the outer electron.
