Answer 2

Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size. The most familiar examples of material particles are the electron, the proton and the neutron. Combinations of these particles form atoms.

1.Particles of matter are very tiny in size.

2.They have spaces between them.

3.Particles of matter move constantly.
