Learning Outcomes for Atomic Theory and Periodic Table
S3 Chemistry
 Identify the 3 sub atomic particles in an atom
 State the location, charge and mass of each sub atomic particle
 Calculate the number of protons, neutrons and electrons in an atom
 Identify whether a species has an equal or unequal number of protons
and electrons and use this to state whether it is an atom or ion.
 State the charge of an ion.
 Calculate the charge on a ion using nuclide notation
 Use the periodic table to identify whether an element is a metal or
non-metal
 State that elements are listed in the periodic table in order of
increasing atomic number
 State that some groups contain elements with similar chemical
properties
 State the definition of an isotope
 Appreciate the varying stability and practical application of isotopes
 Describe the relationship between relative atomic mass and isotopes

covalent structures
 State that ionic substances form giant lattices of oppositely charged
ions and predict the typical properties of ionic substances

 Examples of acids and alkalis you would find in everyday
life.
S3 Chemistry

2. The effect of soluble non-metal oxides on the pH of
water.
3. The environmental impact of non-metal oxides dissolving
in rain water.
4. The effect of soluble metal oxides on the pH of water.

6. Uses of acids in food and drink and their impact on
health.
7. Acids contain aqueous hydrogen ions, H+(aq).
8. Dissociation of water into hydrogen and hydroxide ions.
9. pH is related to the concentration of hydrogen and
hydroxide ions in pure water, acids and alkalis.
