- Bonding & Formation of Molecules
- Ionic Bonding
- Weaker than covalent bonds
- Opposite charges attract
- Electrostatic Attraction
- Covalent Bonding
- Shared pair of electrons
- Outer shell of both atoms filled - stable
- Molecule formed
- Hydrogen Bonding
- Molecule with uneven distribution of charge = polarised (polar molecule).
- Negative region of polar molecule and positively charged region of another attract.
- Weak electrostatic bond formed.
- Each bond individually weak
- Collectively form important forces, that alter physical properties of molecules.
- Electrons within molecule NOT evenly distributed, but spend more time at one position.
- This region is more NEGATIVELY CHARGED than rest of molecule.
- Ionic Bonding
