When magnesium reacts with water, it forms magnesium hydroxide, Mg(OH)2.

Calcium chloride is commonly used as a desiccant due to its hygroscopic nature.

Calcium chloride (CaCl2) is commonly used as a drying agent due to its hygroscopic nature.

Zinc reacts with hydrochloric acid (HCl) to produce hydrogen gas.

Lithium (Li) has the highest ionization energy among the alkali metals due to its smaller atomic size.

Lithium (Li) has the highest melting point among the alkali metals due to its smaller size and stronger metallic bonding.

Sodium (Na) is an alkali metal, while Magnesium (Mg), Calcium (Ca), and Barium (Ba) are alkaline earth metals.

Calcium is a member of the alkaline earth metals, which are found in Group 2 of the periodic table.

Aluminum (Al) is not an alkaline earth metal; it is a post-transition metal.

Potassium (K) has the lowest melting point among the alkali metals.

Aluminum (Al) is not an alkaline earth metal; it is a post-transition metal.

Beryllium (Be) is the lightest alkaline earth metal.

Rubidium (Rb) is the most electropositive element among the given options.

Potassium (K) is more reactive than Sodium (Na) and Lithium (Li) due to its larger atomic size and lower ionization energy.

Alkali metals are good conductors of electricity due to the presence of free-moving electrons.
