1.17 Relative atomic mass
1.17 Activity 2. Calculating relative atomic mass. Students should: 1.17 be able to calculate the relative atomic mass of an element (Ar) from isotopicabundances. Sorting by mass A mass spectrometer is an instrument which can separate and sort the particles in a sample of an element according to their mass. The output from a ...
1.16 Isotopes
1.16 Activity 1. Three types of carbon atom Students should: 1.16 know what is meant by the terms atomic number, mass number, isotopes and relative atomic mass (Ar). Use this animation to explore the number and type of sub atomic particles which make up the three isotopes of carbon. Use the information to complete a copy of th...
1.15 Subatomic particles
1.15 Sub atomic particles Students should: 1.15 know the structure of an atom in terms of the positions, relative masses and relativecharges of sub-atomic particles. Here we look at the particles inside the atom. Sub atomic particles are the particles found inside atoms. These include protons, neutrons and electrons: protons a...
