Sodium (Na) is an s-block element as it is in Group 1 of the periodic table.

S-block elements have low electronegativity.

Alkaline earth metals typically form basic oxides.

S-block elements typically form ionic bonds due to their tendency to lose electrons.

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

Alkaline earth metals have a higher density than alkali metals.

Calcium is not an alkali metal; it is an alkaline earth metal.

Aluminum is not an s-block element; it is a p-block element.

Cesium (Cs) is the heaviest alkali metal.

Lithium has the highest melting point among the alkali metals due to its small size and strong metallic bonding.

Mercury is a liquid at room temperature, but it is not an s-block element; however, among the options, it is the only liquid.

Sodium, calcium, and potassium are all essential s-block elements for human health, playing vital roles in various physiological processes.

Magnesium forms a protective oxide layer that prevents further oxidation.

Lithium is widely used in batteries, especially in rechargeable lithium-ion batteries.

Lithium is the least reactive among the alkali metals.

Rubidium is the most reactive among the s-block elements listed.

Lithium is the least reactive among the alkali metals.

Lithium is used in fireworks to produce a bright red color.

Lithium (Li) is used in fireworks to produce a bright red color.

Sodium is commonly used in fireworks for its bright yellow color.

Beryllium forms covalent compounds due to its small size and high ionization energy.

S-block elements have one or two electrons in their outermost shell.

Rubidium (Rb) has the highest atomic radius among the given s-block elements.

Lithium is used in fireworks to produce a bright red color.
