Chapter 1 : MATTER
1.1 Atoms and Molecules
1.2 Mole Concept
Learning Outcome
At the end of this topic, students should be able :
(a) Identify and describe proton, electron and
neutron as subatomic particle.
(b) Define proton number, Z, nucleon number, A
and isotope. Write isotope notation.
(c) Define relative atomic mass, Ar and
relative molecular mass, Mr based on
the C-12 scale.
(d) Sketch and explain the following main
components of a simple mass
spectrometer.
(e) Analyse mass spectrum of an element.
Calculate the average atomic mass of
an element given the relative
abundance of isotopes or a mass
spectrum.
