Chemistry

Atomic structure:

• Define the following terms; atom, ion, element, compound, molecule, mixture

• Calculate the number of protons, neutrons and electrons in an atom

• Calculate an atom’s atomic number and atomic mass

• Basic structure of an atom including shells

• Determine an atom’s or ions electron arrangement (up to Ca,  Ca²⁺)

Periodic Table:

• Know how to identify metals and non-metals from the periodic table

• Know the names of key groups on the periodic table (e.g Gp 17 are the halogens, Gp 18 are the noble gases, etc)

• Basic understanding of PT structure (including Groups, Periods, metals, non-metals and metalloids)

• Identify reasoning for the position of elements within the PT, including reactivity or stability.

Bonding:

• Identify that ionic bonding occurs between metals and non-metals

• Identify covalent bonding occurs between non-metals

• Use electron shell diagrams to show stability during ionic and covalent bonding

• Know the formulas of simple common covalent species: hydrogen, oxygen, carbon dioxide, water

• Identify metallic bonding occurs within/between metals

• Properties of metals (lustrous, malleable, good conductors, etc)

• Name and write formulae for basic ionic compounds

Chemical reactions:

• Be able to write word equations to represent a chemical reaction 

• Use solubility chart to predict whether a precipitate is formed from various ionic solution combinations

• Be able to write and balance precipitation equations (including states)

• Be able to write and balance equations for reactions between metals and oxygen as well as metals and water

• Describe observations for chemical change with respect to precipitation reactions and metal reactions

• Explain the impact of the following changes on the rate of reaction using collision theory:

• Surface area of solids

• Concentration of solutions

• Temperature

• Catalysts
