Question: A pure substance can be defined as this
Answer: A SUBSTANCE CONTAINING ONLY ONE TYPE OF PARTICLE
Question: Impure substances can be divided into these two types.
Answer: SOLUTIONS AND MECHANICAL MIXTURES
Question: Pure substances can only be be separated in this manner.
Answer: BY CHEMICAL MEANS
Question: These are three methods of separating mixtures by physical means
Answer: FILTER, MAGNET, CENTRIFUGE, DISTILLATION, EVAPORATION
Question: This is an example of a solution consisting of two or more solids.
Answer: "WOOD'S METAL", BRASS, "YELLOW GOLD", THE "NICKEL"
The Quest for Stability
Question: Atoms are neutral in this situation
Answer: WHEN THE # OF PROTONS EQUALS THE # OF ELECTRONS
Question: This is the way in which an ion is formed
Answer: ATOM GAINS OR LOSES ELECTRONS
Question: Ionic bonding only occurs between these two types of elements
Answer: METAL AND NON-METAL
Question: A Magnesium ion would have this charge
Answer: 2+
Question: Covalent bonding is when this occurs
Answer: NON-METAL ATOMS SHARE ELECTRONS

Answer: VALENCE ELECTRONS
Question: These are two ways in which you know a physical change of matter has occurred.
Answer: NO NEW SUBSTANCE IS FORMED, SUBSTANCES HAVE NOT CHANGED, CHANGES CAN BE REVERSED...etc.
Question: These are two ways in which you know a chemical change of matter has occurred.
Answer: NEW SUBSTANCE IS FORMED, CHANGE IS DIFFICULT TO REVERSE, NEW COLOUR IS FORMED, LIGHT IS CREATED
