Nucleus
The center of an atom. It contains two particles: neutron and proton. Has a positive charge.

3 main subatomic particles are the proton, neutron and electron.
THESE particles are SMALLER than an atom.
***LOOK at the difference in size!!! WOW…an electron is SO SMALL!!!

Valence Electrons – the electrons in the outermost energy level/shell of an atom; they determine how an element will react with other substances.

Why does the atom have a neutral charge?
The number of protons in the nucleus of an atom equals the number of electrons orbiting the nucleus.
