10 Elements – made of one type of atom e.g. Carbon, Oxygen Compounds – made of two types of atom bonded together e.g. Carbon dioxide, Magnesium oxide Mixture – made of 2 substances not chemically bonded and can be separated e.g. salt water

11 NH 3 CO 2 O2O2 CuO Mg C2H6C2H6 H2H2 C C 6 H 12 O 6 1.Name whether its an element or compound. 2.Decide how many atoms each has.

12 Q1 How many different types of atom are there in a jar of pure sulfur Q2 What are the symbols for the following elements: Iron, copper, oxygen, sodium, chlorine, aluminium, calcium, carbon. Q3 How many atoms in CaCO 3. How many elements? Q4 Is salt water an element compound or mixture explain your answer Q5. What is shared or transferred when atoms bond together

13 Review Objectives I still feel unsure. I need some more help to understand. I feel ok. I need to do some more work to check my understanding. I am happy and feel I understand and can explain the main points. Keywords: Atom, Element, Electron, Nucleus, Proton, Neutron. To know what is meant by an atom. To know that an atom is made up of three smaller particles. To be able to draw the atomic structure of an atom.
