*Chromatography* - Ans .-Chromatography is a method used by chemists to separate out mixtures. -Chromatography works because different dyes move up the paper and different rates. -Some will stick to the paper and others will dissolve more readily in the solvent and travel more quickly. -You can com[are different chromatograms to work out what dyes are in the unknown substance. *Ionic Bonding* - Ans .-In ionic bonding, atoms lose or gain electrons to formed charged particles which are...

Maximum electrons per shell Electon shell 1: 2 2: 8 3: 18 4: 32 Orbitals A region in an atom where there is a 95% probability of finding electrons. An orbital can hold a maximum of 2 electrons. electron configuration the arrangement of electrons in an atom Spin Electrons spins in opposite directions.
