Study the variation in the atomic radii of second group elements are given below and answer the question given. In the second period which element has the highest metallic characteristics?

In the second period lithium has the highest metallic character. Li, lithium is a chemical element with an atomic number 3 . It is a soft, silvery-white alkali metal. The effective nuclear charge acting on the valence shell electrons increases across a period, the tendency to lose electrons will decrease. Hence, the metallic character decreases across a period.

Study the variation in the atomic radii of second group elements are given below and answer the question given. In this second period of elements which element has the smallest atomic size?

In this second period of elements fluorine (F) has the smallest atomic size. Fluorine is a chemical element with the atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. In general, the atomic radius decreases as we move from left to right in a period with an increase in the nuclear charge of the element.
