1Atoms 1) Describe what an atom is. Lesson aims:-1) Describe what an atom is.2) Compare the atoms in an element andnon-element.3) Give the symbols of some of the mainelements.4) Describe how atoms join to each other to makeelements and non-elements.
2Elementary dear Watson! What is an atom?The word atom comes from the Greek word ‘atomos’ and means ‘can’t be divided up.’Atoms are particles that cannot be broken down into anything simpler.Elementary dear Watson!Fe
3Each atom has its own symbol found on the Periodic table.
4Elements & Non-Elements Elements contain one type of atomMgMgMgMgMgMgMgMgNon-elements contain different types of atomsCuO
5Joining atoms together Atoms can be joined (Bonded) together to make elementsand non-elements.Make some element and non-element molecules using themolymod kits provided.RULE: No balls (atoms) should have any holes withoutsticks in them.Were any models the same?You should see how a few ‘building blocks’ (atoms) can make a whole range of different substances.Can you identify which models represent elements and which non-elements?
