- CHEMISTRY C2
- Structure and Bonding
- Chemical Bonding
- Elements react to form compounds by gaining/losing electrons
- Atoms in Group 1 combine with atoms in Group 7 to form ions
- Ionic Bonding
- Held together by strong forces
- Ions form a giant structure called a lattice
- Formulae of Ionic Compound
- Charges on the ions in ionic compounds always cancel each other out
- Formula shows the ratio of ions present
- Covalent Bonding
- Formed when 2 atoms share a pair of electrons
- Number of covalent atoms formed depends on number of electrons needed to achieve a stable electronic structure
- Most contain simple molecules, but some have giant covalent structures
- Metals
- Atoms in metals are closely packed and arranged in regular layers
- Electrons in the highest energy level are delocalised. Strong electrostatic forces between the electrons and positive ions hold the metal together
