How does the atomic radius of an element is related to its metallic character

The large the atomic radius the more the metallic character of elements

Explanation:

The atomic radius is related to the metallic character in a way that the larger the atomic radius, the more metallic a body becomes.

Therefore, as we go down a group, metallic character increases.

Metallic character relies on the ability and willingness of an atom to share its valence electrons. As the size of an atom becomes large, the more metallic it is and the more its metallic character. In some other cases this character is known as electropositivity.
