The electron configuration of an element is shown below. 1s22s22p63s23p6 name the group this element belongs to in the periodic table and explain your answer. based on the electron configuration, write one chemical property of this element.

Answer : The element belongs to group 18 in the periodic table and the chemical property of argon element is that it is an unreactive element.

Explanation:

Period : A row in the periodic table is known as period.

Group : A column in the periodic table is known as group.

The given electronic configuration is,

Number of electrons = 2 + 2 + 6 + 2 + 6 = 18 electrons

And as we know that atomic number is equal to the number of electrons. So, the atomic number is, 18 and argon is the element that has atomic number 18 and it belongs to p-block. The rule for determining the group number for p-block is,

Group number = no. of valence electrons + 10

The number of valance electrons = 2 + 6 = 8

Group number = 8 + 10 = 18

Hence, the element belongs to group 18 in the periodic table.

The chemical property of argon element is that it is an unreactive element.
