Dear Year 12,


I am still recovering from laryngitis and hope to see you on Monday.

For today's lesson we will be starting a new topic

Module 3 - Periodic table and energy

I would like you to read the spec point below

Periodic trends are first studied to extend the understanding of structure and bonding.

3.1.1 Periodicity 
Learners should be able to demonstrate and apply their knowledge and understanding of: 
The structure of the periodic table 

(a) the periodic table as the arrangement of elements:
(i) by increasing atomic (proton) number
(ii) in periods showing repeating trends in physical and chemical properties (periodicity)
(iii) in groups having similar chemical properties

Periodic trend in electron configuration and ionisation energy

(b) (i) the periodic trend in electron configurations across Periods 2 and 3 (see also 2.2.1 d)
(ii) classification of elements into s-, p- and d-blocks
(c) first ionisation energy and successive ionisation energy, and:
(i) explanation of the trend in first ionisation energies across Periods 2 and 3, and down a group, in terms of attraction, nuclear charge and atomic radius
(ii) prediction from successive ionisation energies of the number of electrons in each shell of an atom and the group of an element

I would like you to make notes on the above points ready for Monday's lesson. On MOnday I will give you some exam style questions to test your understanding.

I would use the Chemguide website which always has lots of information to help you understand.
Also Khan academy do some really good videos that explain different concepts in chemistry.

Hope you all have a good weekend

Many Thanks

Miss Chauhan

Welcome Year 12!

Here is your homework for ERA:

1. Read and make notes on two pieces of writing:

This piece I’m giving you now - Chemistry 1010: Atomic Orbitals

…and the information that you find when working through the chapter “It’s Elementary” on this website https://www.learner.org/interactives/periodic/elementary3.html

Evaluate the two sources – which was more useful? Which was easier to use?

2.  Complete the Building Elements activity at the end of the chapter on the website above.  Make a note of the electron configurations you found.

LEL interviewing tomorrow - not in

Dear all,

I am not in tomorrow - I am interviewing YET AGAIN. I'm sorry about this.

Whilst you are enjoying your free time you could have a look at school chemistry review and read the latest edition

LEL away on Thursday

Dear 12eCh and 12dCh,

I am away on Thursday - I'm interviewing so will be around but not able to be in the lesson. In my absence could you please investigate the development of the model of benzene and produce some succinct notes. You need to be able to:

1. Describe the kekule structure of benzene
2. Explain the evidence for and against the kekule structure of benzene
3. Describe the orbital model of of benzene
4. Explain the evidence for the orbital model of benzene

I will go over it in class by picking on you and expecting you to know something about it!

Have a nice day without me.

Yours

Ms Elias

cover for period 2 today

You need to answer some of the exam questions that I have posted on the blog (below) – there are 504 minutes worth in total (if you ignore any overlaps). Some questions have come out a little weird and it is impossible to read the scale (so don’t do those) and you’ve not learnt anything about fermentation – so ignore these questions too!

Have fun without me. I’ve booked the library computers for your use (not the ones on the stage) so you could ask Mrs Cook to boot the other 6^th formers out. 

Practice Exam Questions for Module 4

In total this is 504 minutes worth of questions!

Cover work for 12e on 12th May

Apologies I will not be able to see you today.

Please read pages 146-147 of the text book and answer the questions on page 147.  There is graph paper on the door of W9 which you will need to do this.

Please also complete the worksheet on rates and collision theory (also stuck on the door).

PAG 5.1 for LEL Y12 Chemists

Good afternoon,

12dCh and I discovered, this morning, that PAG5.1 does not work. The mixture does not separate, even following some intervention with other solvents and by trying to "salt it out". This means that we will not be doing PAG 5.1 on Wednesday or Friday and will instead be starting PAG5.2.

If you read this message before the lesson please don't complete your homework and instead we will assess the risk of the chemicals at the start of the lesson, as the DNA.

Yours
Ms Elias

Updated shared work

You can now find all the lesson materials (up to today's date) in the module 4 folder...

Y12 Chemistry Class

I’m sorry I am not in school this week. I intend to be back on Monday but whilst I am away please use the two hours that you would have spent with me reading up and making notes on testing for positive and negative ions. You will need to be able to use these tests confidently to identify a variety of unknown compounds in a practical assessment in the week before ½ term. This practical assessment will not contain details on how you carry out the tests, nor on how to interpret the results – you will need to work this out for yourself on the day.

You need to be able to test for the following substances, and write equations for these tests:

·         Carbonate ions (with acids)

·         Sulphate (VI) ions

·         Nitrate (V) ions

·         Halide ions (with aqueous silver ions followed by aqueous ammonia)

·         Sodium, Lithium, Potassium, Calcium, Strontium, Barium and Copper ions (with flame tests)

·         Copper (II), Iron (II) and Iron (III) ions (with sodium hydroxide)

·         Magnesium, Calcium, Aluminium and Ammonium (with sodium hydroxide, including the use of litmus paper where necessary)

Use your textbook, although I don’t have a copy at home and can’t give you the page numbers. You should also look at:

·         http://www.docbrown.info/page13/ChemicalTests/ChemicalTests.htm

·         http://www.ocr.org.uk/Images/208563-identifying-unknowns-delivery-guide.pdf (some parts of this document)

·         http://www.chemguide.co.uk/inorganic/group7/testing.html

·         http://www.chemguide.co.uk/inorganic/group1/flametests.html

·         http://www.chemguide.co.uk/inorganic/transition/iron.html

If you’re totally stuck I’m happy to help by email.
