- Differentiate between an atom, an element, a compound, a molecule and subatomic particles; given a list of such terms, he/she should be able to match them with appropriate phrases or synonyms – selecting at least 10 of a choice of 15 possibilities.
- Determine the pertinent characteristics (atomic number, atomic mass, location of protons, neutrons, electrons) of 15 of the first 20 elements in the periodic table.
- Indicate the relative chemical activities of eight out of ten of a given list of atoms (such as hydrogen, helium, boron, carbon, nitrogen, oxygen, sodium, chlorine, potassium, and calcium).
- Given at least three of five possible features of a theoretical atom – state the atomic mass and number.
- Indicate the chemical and biological significance of isotopes, selecting two from a list of five supplied to him/her.
- Define and give examples of electrovalence, covalence, non polar, and polar covalent bonds, ionic bonding and hydrogen bonding.
- Contrast between and give four (4) examples of inorganic and organic compounds of biological significance.
