But just how small is an atom? – from TED-Ed.
Here are some key terms for this topic: Key Terms C3
C3.1 PHYSICAL & CHEMICAL CHANGES
C3.2 ELEMENTS, COMPOUNDS & MIXTURES
C3.3 ATOMIC STRUCTURE & THE PERIODIC TABLE
A decent power-point, although we do not need to know about isotopes:
Short videos on what is an atom and parts of an atom (from The Virtual School) in English; and here’s one in Australian. Science Bank 17 (Atomic Structure):Part 1 – structure of the atom, Part 2 – atomic number & mass number, Part 3 – electronic structure.
The Virtual School have made a number of other short videos. Here’s one on atomic & mass number; this covers energy levels & electronic configuration. Some practice exam questions on atoms go here and here. And here’s a poem.
GCSE s-cool – Atomic Structure – revision notes & animations, practise exam questions & a revision summary. Skoool Chemistry – click on ‘5. Atoms & the Periodic Table’ for excellent lessons that take you through atomic structure; also a glossary of key terms. For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down to ‘17.Atomic structure, isotopes, electronic structure’.. Chemactive worksheets & answers just click on ‘Atomic Structure questions’.
C3.4 IONS & IONIC BONDS
C3.5 MOLECULES & COVALENT BONDS
A 15m lesson covering Ionic, Covalent & Metallic bonding from ChemistryKlipz (you don’t need metallic bonding in this topic):
A nice review of bonding and here’s a song:
And now we need another song. Oh, here’s Mr W singing his Octet Rule Song.
Revision sites covering Bonding:
GCSE s-cool – Chemical Bonding – revision notes & animations, practise exam questions & a revision summary. For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down to ‘18.Structure, Properties and Bonding of Materials’.
Skoool Chemistry – click on ‘1. Structures & Bonding’ for excellent lessons that take you through the topic; also a glossary of key terms. Worksheets from Mr Guch that cover Properties of Ionic & Covalent Compounds.
