Question

When an atom exists in the nature without forming a molecule with similar or different atoms, what
is the atomicity of the element?

(A) Atomicity is 2
(B) Atom cannot exist in nature by itself
(C) Atomicity is 1

Answer 1

Answer:

Option A is false. Atoms are not able to exist independently. All the elements on the far right side of the periodic table (inert or noble gas) atoms can exist independently because they all fulfil the octet rule. They do not need bond to become stable.

Option B is true. Atoms are the basic units from which molecules and ions are formed. A molecule is comprised of two or more chemically bonded atoms. The atoms may be of the same type of element, or they may be different. Atoms can readily gain or lose electrons. If electrons are lost or gained by a neutral atom, a charged particle is formed called as an ion.

Option C is true. Atoms are always neutral in nature. The nucleus of an atom (contains protons and neutrons) remains unchanged after ordinary chemical reactions, but atoms can readily gain or lose electrons.

Answer 2

Answer:

atomicity is 1
