polymers and alloys

what are polymers made up of, and how do you draw them?

repeat units; when drawn, the bonds must extend outside of the bracket. an n is also written in the bottom right corner

why are the mps and bps of metals so high?

strong electrostatic forces of attraction between positive metals ions and negative delocalised electrons within the metal lattice. needs lots of energy to overcome

compare alloys and metals

alloys are stronger, harder

alloys are resistant to corrosion and extreme temperatures

why are alloys stronger than metals?

the different sizes of atoms cause the layers in the substance to become distorted. therefore it is more difficult for the layers of atoms to slide over one anothe
