• Isotopes are atoms with the same number of protons but different neutrons.

The Periodic Table

• Organized by increasing atomic number.
• Elements are grouped into periods (rows) and groups (columns).
• Elements in the same group have similar chemical properties.
• Key groups: Alkali metals (Group 1), Halogens (Group 7), Noble gases (Group 0).

Chemical Bonding

• Ionic bonds: formed between metals and non-metals.
• Covalent bonds: formed between non-metals.
• Metallic bonds: between metal atoms.
• Properties depend on type of bonding: melting point, conductivity, solubility.
