Question

like lithium and potassium have low melting points.

• A. Alkali metals
• B. Non-metals
• C. Noble metals

Answer 1

The correct option is A Alkali metals

Lithium, sodium, potassium, rubidium, and caesium are alkali metals. These metals are found in the group 1 of the periodic table. They have one electron in their outermost shell and are very reactive (can get ionized easily). They are soft, have low densities and low melting points.

Noble metals (gold and platinum) are those metals which are very unreactive. Non-metals have high melting points and usually exist in gaseous or solid states.
