Question

There are $11$ gaseous non-metallic elements in nature.
A) True
B) False

Answer 1

Hint: Metals, non-metals, and metalloids are the three types of elements in nature. Metals are excellent heat and electricity conductors, as well as being malleable and ductile. Non-metals are weak heat and energy conductors. Metalloids have properties that are somewhere in the middle of metals and non-metals.

Complete step-by-step answer:
Non-metals are elements that accept or gain electrons to form negative ions. The outermost shell of non-metals normally has $4,5,6$ or $7$ electrons. Natural materials that do not contain heat or electricity and are structurally brittle are known as non-metals (cannot be easily rolled, moulding, extruding or pressing).

These atoms are usually smaller than metal atoms. They have a tendency to be porous in their stable state. As a result, they lack the malleability and ductility that metals have. Some non-metals are found as gases, others as solids, and one is found as a liquid

The non-metallic elements in the periodic table are Hydrogen (H), Nitrogen (N), Oxygen (O), Fluorine (F), Chlorine (Cl), Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Rn). Hence, the statement is correct; there are $11$ gaseous non-metallic structures in nature.

Therefore, Option (A) True is the correct answer.

Note: Due to a rise in nuclear charge and a decrease in atomic size, the tendency to gain electrons increases as we move across the periodic table. As a result, the non-metallic character rises across a period. The non-metallic character reduces as we go down the group due to atomic size increases.
