element The smallest part of a chemical element that has all the properties of that element is the atom. electrons, protons, neutrons Everything in our world is made up of electrons, protons, and neutrons.

Nucleus Nucleus: Protons & Neutrons if an atom was the size of a football stadium, then a proton would still be smaller than a marble.

Protons All protons are exactly the same and are found inside atoms. They have a p ositive charge different how manyDifferent atoms have different numbers of protons ; what makes an atom be a helium or a gold atom depends on how many protons it has. atomic mass unitThe mass of the proton is equal to 1 atomic mass unit (amu) an atom has equal numbers of protons And electrons

Neutrons sub-atomic particle hydrogenThe neutron is a sub-atomic particle of the atom and is found in all elements except hydrogen. It has a neutral charge. neutronprotonmassThe neutron and the proton make up the mass of the atom. neutronWithout the neutron, the protons would push away from each other.

Electrons cloudsElectrons are found in clouds that surround the nucleus of an atom. They have a negative charge specific distances shells (levels)Those clouds are specific distances away from the nucleus and are organized into shells (levels) using the configuration. move impossibleBecause electrons move so quickly, it is impossible to see where they are at a specific moment in time.
