atomic mass - ANS- the total number of protons and neutrons
atomic number - ANS- the number of protons and electrons
cation - ANS- positively charged ion
compound - ANS- elements that are chemically joined together
condensation - ANS- changing state from a gas to a liquid
covalent bonding - ANS- sharing of electrons between to non- metals.
E.g ammonia NH4(nitrogen in middle and four hydrogen surrounding)
crystallisation - ANS- solutes which have dissolved in solution are separated by
evaporating solvent, to leave solutes behind. The longer left to cool the larger the
crystals
deposition - ANS- changing state from a gas to a solid
electron - ANS- - a negatively charged particle
- has a mass 1/2000
- found in energy levels which surround the nucleus.
electron configuration - ANS- 2,8,8..
E.g magnesium has an atomic number of 12 so its electron configuration will be 2.8.2
electrostatic forces - ANS- strong forces of attraction between oppositely charged
particles
evaporating and boiling - ANS- changing state from a liquid to a gas
examples of simple covalent compounds and their properties - ANS- - methane
- oxygen
- water
