Question

Matter is made up of particles

Answer 1

All matter is made up of particles called atoms and molecules (as opposed to being continuous or just including particles).
A glass of water, for example, has many water particles, each too small to see…. Water particles can actually be divided into even smaller units. The pieces of matter that result from dividing a water particle are no longer water. They are examples of the most basic units of matter called atoms
These particles are extremely small—far too small to see directly through a microscope.
