- The Atom
- Proton
- Relative charge: +1
- Relative mass: 1
- Location: the nucleus
- Neutron
- Relative charge: 0
- Relative mass: 1
- Location: the nucleus
- Electron
- Relative charge: -1
- Relative mass: 0.00055
- Location: shells
- Mass number
- The top number
- A
- The number of protons and neutrons in the nucleus
- Atomic number
- The bottom number
- Z
- The number of protons in the nucleus
- Which equals the number of electrons
- Isotopes
- Atoms with the same number of protons and electrons but different numbers of neutrons.
- The isotopes do the same chemical reactions as they have the same number of electrons in their outer shell.
- They have different physical properties, such as mpt, bpt, and rate of reaction because they have different masses.
- Proton
