We are going to review some more GCSE Chemistry and then baseline test you later in the week. This is what we would do in the first week of a sixth from course. It is called transitioning. You will have some homework to do, which will extend this work and take you wider than the AS/A-level specification. This is listed on this page. Are we ready?

This is the progression you will make in these two lessons.
TASKS 1 - 7 ARE 'MUST DO' TASKS AND
TASK 8 IS OPTIONAL/EXTENSION/COULD DO.
THIS IS NOT A VC LESSON BUT THE FORUM IS OPEN TO ASK QUESTIONS AND RECEIVE LIVE ANSWERS.
TASK 1: To look at ionic bonding by watching the videos below.
TASK 2: Use the summary sheets below to help you take on board and learn all key basic points about ionic bonding from the KS4 course. PLEASE STUDY CAREFULLY!
TASK 3: Now study the picture and AS level videos below.
TASK 4: Now try this stretch and challenge question.
a Draw a dot-and-cross diagram to show the structure of the ions in solid aluminium chloride (outer shell only). (2 marks)
b The ionic lattice has a structure in which six chloride ions surround one aluminium ion, in an octahedral arrangement. Draw a 3D diagram to show this arrangement. (2 marks)
c Solid aluminium chloride has the empirical formula AlCl3. Use the information in part b to suggest how many aluminium ions surround each chloride ion in the ionic lattice. Explain your answer. (2 marks)TASK 5: We now need to look at charges on ions and finding and writing formulae of ionic compounds. Watch and learn from the video below.
TASK 6: Now, can you do the following? Sheet 1 is a summary sheet - PLEASE READ CAREFULLY and sheets 2 and 3 are for you to print out, complete and return to me for marking via Firefly. We can go through these together by asking questions via the forum or ask tomorrow in the VC lesson.
TASK 7: Listen to the podcast about Linus Pauling - the only ever scientist to have been awarded two Nobel Prizes, on his own, and in two separate fields - Chemistry and Peace. Click below.
TASK 8: EXTENSION/COULD DO - write a short account of the work of Linus Pauling - it should astound you!
TASK 4 Part c: Hint - look at this picture part
