Biological Molecules Team – Game – Tournament Answers
1. Carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur
2. Atoms have lost or gained electrons to become charged atoms called
ions. Opposite charged ions attract to form ionic bonds
3. Atoms share electrons equally with each other to form covalent bonds
4. Atoms share electrons unequally such that one atom has slightly more
electrons (γ-) and the other atom is slightly fewer electrons (γ+)
5. The attraction of a slightly + H atom of one molecule to a slightly – O
atom of another molecule
6. Liquid at room temperature. Universal solvent. Cohesion of water
molecules. Temperature of liquid water rises and falls slowly. High
heat of vaporization. Frozen water is less dense than liquid water 
ice floats!
