Question

2. All matter is made of small indivisible particles called atom. Atoms, however, do
not have independent existence, in general. They generally exist in combination with
other atoms in the form of molecules or ions. Molecules are thus, smallest particles
of various substances (elements or compounds) which have independent existence.
The number of atoms present in one molecule is called atomicity
(1) Write any specific name given the molecule containing different atoms. (1)
(ii)
Name two elements whose atoms exist independently
(in) Atomicity of a molecule of Nitric acid (HNO).
(iv) Name the element which exhibits the atomicity of 4?
(v) Why it is not possible to see the atom with naked eyes?
(1​

Answer 2

Answer:

atom

Explanation:

An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.
