Atoms are fundamental pieces of matter.
The matter refers to anything that may be touched physically.
Next lesson: Molecules
This transcript is for your convenience. All things in the universe are made of matter (except energy). So all things in our universe are made of atoms. Atoms themselves are made up of three very small sorts of particles named subatomic particles: electrons, protons, and neutron.
The center of an atom (called the nucleus) includes protons and the neutrons while the electrons are flying around above the atom’s nucleus in a tiny cloud.
Electrons are carrying a negative charge while protons are carrying a positive charge.
Within a normal atom (neutral atom), the number of electrons and the number of protons are equal. Usually, but not always, neutrons are here seen in the same number as well.
The atom’s negative electrons are always attracted to the atom’s positive nucleus by the identical electrical force that is causing magnets to work the way they do.
That electrical force is what’s keeping the atom together.
