Which one is not a correct statement about the matter?

A matter is any substance having mass. The matter is mainly classified into three based on its physical state; solid, liquid, and gas. Atoms, which are minute building blocks, make up the matter.

The force of attraction between these particles is highest for solids and lowest for gases.
In solids, the intermolecular space is very low. But in gases the distance is large. So, matter does have space between atoms.
In liquids and gases, particles have freedom of movement. In solids also particles can vibrate to a small extent. Thus particles in the matter are in a state of motion.
Metals, being solid is made up of small particles.
So, the wrong statement in the given options is; option B.

Hence, the correct answer will be option B.
