Matter, Properties, and Phases

Matter is anything that takes up space and has mass.

Matter is made up of many things, but the smallest component within matter is an atom.

Atoms are very small, but they are made of smaller parts.

Atoms are made of protons, neutrons, and electrons.

The protons are the positively charged particles.

The neutrons are particles without charge.

The Electrons are negatively charged particles.

When protons and neutrons stick together they become the nucleus of the atom.

It is virtually impossible to ever track down the exact location of electrons in the atom because they move so fast.

A man named john dalton was the person to make the presumption that there was something smaller within everything that was not visible.

He was the founder of the Atomic Theory of Matter.

He named the non visible particles atoms.

Another man named Joseph John Thomson was the one to discover that there are negatively charged particle.

Another man named Ernest Rutherford discovered that there were positively charged particles.
