- CHEMISTRY- C2 Revision
- Atomic Structure
- PROTONS:
- Posotive +
- Electrons
- Negative -
- Neutrons
- Neutral 0
- Electron Structure:
- 2 In first shell
- 2 in the second shell
- 16 in the third
- PROTONS:
- Ionic Bonds
- Bonds: non metals and metla
- Give and Recing electrons
- During Chemical bonding ions are formed
- Working it out: the number of charges on an ion formed by a metal is equal to the group number.
- Non-metals is group number - 8
- Bonds: non metals and metla
- Convalent Bonds
- Non-metal and Non-metals
- Share electrons
- Atoms all contain noble structure
- New particles formed are Neutral Molocules
- No Charge
- Solid, Liquid and gas at room tempreture.
- Low mealting and boiling point
- Weak atrtraction
- Structure of Substance
- Giant ionic
- Ions held together by strong attractions
- Forces equal in all dirrections in lattice
- Tightly packed ions
- Strong forces between ions
- Giant metallic
- The atoms in metal are in layers
- Slide over each other, make them possible to bend into shape
- Metals consits of posotive charge held together by free electrons
- Strong
- High melting point
- Malleable Ibeaten into diffrent shapes)
- Good conductors of electricity and heat
- Lustrous
- The atoms in metal are in layers
- Giant Convalent
- Large network of bonds
- Strong convalent bonds
- Hard
- High melting and boling points
- Unreactive
- Diamond
- Carbon based
- Each C joins 4 others
- Very hard
- No electrical charge
- Graphite
- Carbon based
- Each C joins to 3 others
- 1 free electron per carbon
- Conducts electricity
- Sand (silicon dioxide)
- Carbon based
- Each silicon joins 4 oxygen
- Each oxygen joins 2 silicon
- Simple Molecular
- Small molociles containing few atoms
- Strong convalent bonding
- Atoms are super strong
- Molocules farily weak
- Low melting & boiling point
- not conduct electricity
- Little strength
- Giant ionic
