Half-term revision on Tuesday

Just a reminder that there will be an extra AS Chemistry revision session this Tuesday, 27th May (i.e. during half-term) from 10am to 12pm.

We will use the time to go through your mock exam paper. Please let me know in advance if there are any areas of the course in particular that you would like to go through.

Easter Revision - Biology and Chemistry

In answer to Lois' post and in case any of the rest of you weren't sure, here are the times of the Biology and Chemistry revision sessions:

Year 12 Chemistry - Thursday, 3rd April (1.30 - 3.00pm) OR 9.30 - 11.00am instead if that works?

Year 12 Biology - Thursday, 3rd April (1.30 - 3.oopm)

Year 13 Chemistry - Wednesday, 2nd April (11.15am - 12.45pm)

Please don't ask me why Mr Sudbery has seen fit to put Year 12 Biology and Chemistry on at the same time. Maths is at 11.15 - 12.00, also on Thursday so we can't put an extra session then, but are there are any takers for 9.30 - 11.00 on Thursday? I'll just need to check that I'm not expected anywhere else at that time.

errr what time is it also does anyone know what time bio is tomorrow

New Email & Stuff

Okay firstly, I have a newer email address (again):
lucindawebb@live.co.uk
which is nice :) add it.

Secondly, I don't like this polarisation of molecules business
does anyone know any websites that explain it?

Ellectrophilic addition

If any one knows the answer....

When, for example Bromine, approaches the ethene molecule, the bromine becomes polarised and the electrons are pushed back. Does this mean it makes an istantaneous dipole?

I was just writing notes and made the link... is that right?
