Mr. Olivas thinks this is him. I don’t get it!

* Smallest part of an element * Has all the properties of the element

* Particle buzzing around the nucleus of an atom * It has a negative charge

* The dense part in the middle of an atom * Has protons and neutrons in it

* The area where electrons move

* The particles in the nucleus that are positive

* The unit that describes what the mass of the atom or molecule is. * Can be found on the periodic table

* The particle in the nucleus of an atom that has no charge but has mass

* The number of protons in the atom

* The same element(atom) that has different amounts of neutrons.

* The number of protons and neutrons in an atom added together

* The mass of an atom expressed in atomic mass units or amu.
