GCSE C2a Key Words

?
Ionic Bonding
Metal Giving a non-metal electrons to have a full outer shell.(8)
1 of 8
Alkali Metals
Found in Group 1, have 1 outer electron, reacts with water. E.G Caesium
2 of 8
Ionic lattice
Strong electrostatic forces hold together ions in a giant lattice. High melting and boiling points.
3 of 8
Multi-atom Ions
Many negative Ions are not single atoms that have lost electrons to become ions, but sometimes several non-metals that are covalently bonded together.
4 of 8
Covalent Lattices
Covalent compounds with giant structures called lattices, includes: Graphite, Diamond, and silicon dioxide.
5 of 8
Thermosoftening
polymer with a tangle of smooth chains, easy to recycle and melt. Easy for molecules to slide past each other.
6 of 8
Thermosetting
Polymer with more side chains and links to other chains, hard for chains to slide at all. Hard to recycle and cannot melt.
7 of 8
HDPE & LDPE
Made from same monomer but by different catalysts, temperatures and pressure giving HDPE and LDPE different properties.
