Question

The elements with atomic numbers 10, 18, 36, 54 are-

A.

Light metals

B.

Inert gases

C.

Rare earths

D.

Halogens

Correct option is B


The correct answer is (b) Inert gases.
· The elements with atomic numbers 10, 18, 36, and 54 correspond to Neon (Ne), Argon (Ar), Krypton (Kr), and Xenon (Xe) respectively.
· These elements are part of Group 18 on the periodic table, known as the noble gases or inert gases.
· Inert gases are characterized by their lack of reactivity due to their complete valence electron shells, making them very stable and unlikely to form chemical compounds under normal conditions.
Information Booster:
· Light Metals: Typically refers to metals such as lithium, beryllium, sodium, and others that are low in density and highly reactive, particularly with water.
· Rare Earths: A set of 17 chemically similar elements, including the lanthanides, plus scandium and yttrium, known for their importance in electronics, magnets, and other advanced technologies.
· Halogens: Elements in Group 17 of the periodic table, such as fluorine, chlorine, bromine, and iodine, known for their high reactivity and tendency to form salts when combined with metals.
