Explanation:

Option A is not correct.

Explanation for Option (A): Atoms are not able to exist independently.

• Atoms can accept or donate electrons to form a stable electronic configuration.

• It results in the formation of the molecule.

• Only inert gases, on the other hand, already have octet-filled configurations, allowing them to exist as atoms.

Explanation for Option (B): Atoms are the basic units from which molecules and ions are formed.

• Two or more two atoms are combined and form a molecule.

• These atoms can be the same or different and based on that the molecules can be homonuclear or heteronuclear molecules.

• When an atom accepts or donates electrons it forms ions.

Explanation for Option (C): Atoms are always neutral in nature.

• An atom has an equal number of protons and electrons.

• So atoms are always neutral in nature.

Explanation for Option (D): Atoms aggregate in large numbers to form the matter that we can see, feel or touch.

• Atoms are very small in size, so can not be seen by naked eyes.

• When atoms are aggregated in large numbers to form matter then we can see, feel or touch.
