Detailed Solution

An element X belongs to the 3rd period and group 2. The nature of an element is metal.

Elements in group 2 of the periodic table are known as the alkaline earth metals.
These elements have two valence electrons in their outermost energy level, which makes them chemically reactive but not as reactive as the alkali metals in group 1.
Alkaline earth metals typically have properties like high melting and boiling points, low electronegativity, and they readily form 2⁺ cations by losing their two valence electrons.
Since X is in group 2, it exhibits the characteristic properties of an alkaline earth metal, which includes being a metallic element.

The group 2 elements are known as alkaline earth metals because they form basic compounds.
An element X belongs to the 3rd period and group 2. The nature of an element is Magnesium.
