- Atomic Structure
- Protons
- Make up the nucleus
- Charge is +1
- No. of protons = no. of electrons
- Mass is approx. 1
- Neutrons
- No charge
- Make up the nucleus
- Mass is approx. 1
- Electron
- Orbits the nucleus in shells
- Charge is -1
- Mass of 1/2000 (none)
- No. of protons = no. of electrons
- Isotopes
- Isotopes are atoms of the same element with different numbers of neutrons
- Different isotopes of the same element react in the same way
- Because chemical reactions involve electrons
- Because the no. of neutrons doesn't affect its chemical reactivity
- Atomic Structures of Ions
- An ion is a +vely or -vely charged atom or (covalently bonded) group of atoms (a molecular ion).
- Ions are formed when atoms react by losing or gaining electrons.
- Protons
