About me

I am studying physics at the University of Manchester. I have been involved in volunteering to organise events for elderly people within my local community. As well as this I have aided in delivering workshops to schools in my local about bullying. 

I will try to teach you in a style that suits you best, so just tell me what you feel helps you and I will do it. As well as this I will use techniques that helped me when I did my GCSEs and A levels. For example, the sessions will be based around exam questions and exam technique as practice is very beneficial. As well as this the use of examiners reports to see where other students have struggled in the past to prevent you from making similar errors, which was something I found really useful.

Questions Rebecca has answered

A sample of pure gold has a density of 19300 kgm^-3. If the density of a gold nucleus is 1.47x10^17Kgm^-3, discuss what this implies about the structure of the gold atom. [4 marks]

To gain all of the marks, 4 different points must be made. To begin, state what is obvious:

The density of the gold nucleus is much greater than the density of the gold atom.

The next step is to discuss what this means. As the gold nucleus is inside of the gold atom, this implies that the majority of the mass of the atom is concentrated within the nucleus.As density is mass per unit volume, a high density but a small mass shows that the volume must be incredibly small. This shows the nucleus is small compared to the size of the atom.And finally, this shows that the atom contains a lot of empty space.
