Negatively charged Particle
Mass:  Almost Nothing

• Protons
• Neutrons
• Electrons
• Isotopes

The total number of Protons and Neutrons.

• Mass Number
• Atomic Number
• Matter
• Ion

Number of protons in an atom.

• Atomic Number
• Mass Number
• Isotope
• Valence electrons

Subatomic particles consist of 

• protons and electrons only
• neutrons and protons only
• electrons and neutrons only
• protons, neutrons, and electrons

The best way to define an atom is

• the basic particle from which all others are made
• a pure substance that cannot be broken down further
• neutrally charged particle inside the nucleus
• positively charged particle inside the nucleus
