1. know the structure of an atom in terms of electrons, protons and neutrons
2. know the relative mass and relative charge of protons, neutrons and electrons
3. know what is meant by the terms ‘atomic (proton) number’ and ‘mass number’
4. be able to determine the number of each type of sub-atomic particle in an atom, molecule or ion from the atomic (proton) number and mass number
5. understand the term ‘isotopes’
6. be able to define the terms ‘relative isotopic mass’ and ‘relative atomic mass’, based on carbon-12
7. understand the terms ‘relative molecular mass’ and ‘relative formula mass’, including calculating these values from relative atomic masses
Definitions of these terms will not be expected.
The term ‘relative formula mass’ should be used for compounds with giant structures.
8. be able to analyse and interpret data from mass spectrometry to calculate relative atomic mass from relative abundance of isotopes
9. be able to predict the mass spectra, including relative peak heights, for diatomic molecules, including chlorine
10.understand how mass spectrometry can be used to determine the relative molecular mass of a molecule
Limited to the m/z value for the molecular ion, M+, giving the relative molecular mass of the molecule.
11.be able to define the terms ‘first ionisation energy’ and…
