Ans: b
Explanation: Atom is the smallest particle of an element that can take part in a chemical change. It is the smallest particle of an element which does not always exist independently. For example atoms of hydrogen do not exist indecently but instead always occur in pairs. Two atoms of hydrogen form a molecule of hydrogen which exists independently.
Atomicity is the number of atom present in a molecule of an element. Atomicity of hydrogen, oxygen nitrogen and is 2, for ozone it is 3 and phosphorus it is 4.

Explanation:
The statement "Atom is the smallest particle of an element which can exist independently" is not true.
Atoms:
- Atoms are the basic building blocks of matter.
- They are the smallest particles of an element that retain the chemical properties of that element.
- Atoms cannot exist independently in nature. They always combine with other atoms to form molecules.
Molecules:
- Molecules are formed when two or more atoms chemically combine together.
- Molecules are the smallest particles of a substance that can exist independently and still retain all the chemical properties of that substance.
Explanation of the given statements:
a) Atom is the smallest particle of an element that can take part in a chemical change.
- This statement is true. Atoms participate in chemical reactions by exchanging, gaining, or losing electrons.
b) Atom is the smallest particle of an element which can exist independently.
- This statement is not true. As mentioned earlier, atoms cannot exist independently. They always combine with other atoms to form molecules.
c) Two atoms of hydrogen form a molecule of hydrogen which exists independently.
- This statement is true. Two hydrogen atoms combine to form a molecule of hydrogen (H2) which can exist independently.
d) Atomicity is the number of atom present in a molecule of an element.
- This statement is true. Atomicity refers to the number of atoms present in a molecule of an element. It can be 1, 2, 3, or more depending on the element and the molecular structure.
Conclusion:
In conclusion, the statement "Atom is the smallest particle of an element which can exist independently" is not true. Atoms cannot exist independently; they always combine with other atoms to form molecules.
