Periodic Table

Structure of an atom
1. Electrons
  1. Atomic no. = no. of electrons
2. equal no. of protons and electrons = neutrally charged
3. Nucleus
  1. Neutrons
    1. Atomic mass - atomic no.
  2. Protons
    1. Atomic No.
Properties of elements
1. Metalloids
  1. Brittle
  2. Poor Conductors
  3. Lustre or Dull
2. Non-Metals
  1. Dull
  2. Brittle
  3. Insulators
3. Metals
  1. Malleable
  2. Ductile
  3. Conductors
  4. Lustre
Made up of
1. Groups
  1. No. of electrons in outershell
2. Periods
  1. No. of shells in an atom
TYPES OF BONDING
1. Ionic Bonding
  1. Metals & Non-Metals
    1. Cations & Anions
  2. Non-metals gain electrons
    1. More electrons less protons
      1. Overall negative charge
  3. Metals lose electrons
    1. More protons less electrons
      1. Overall positive charge
2. Covalent Bonding
  1. Can be modelled using electron dot diagram
  2. Share electrons to fill outer shells
    1. Will form...
      1. Single Bond
      2. Double Bond
      3. Triple Bond
  3. Non-Metal & Non-Metal
