What materials make up elements?

Atoms

• The smallest unit of matter.

1) Proton - positively charged particle located
in the nucleus. 2) Neutron - particle
located in the nucleus with no charge.
3) Nucleus - central portion of an atom
that comprise the majority of the atoms
mass. Contain both protons and neutrons.
4) Electron - negatively charged particle located
in the surrounding energy levels.
5) Energy Level - shells that surround the
nucleus that contain the
electrons.
