AQA GCSE Chemistry
| Front | What happens to the boiling point of group 0 (noble gases) as you go down the group? Why? |
| Back | The boiling point increases because there is an increase in the number of electrons in each atom, which leads to greater intermolecular forces between them, which are hard to overcome, therefore it requires a lot of energy. |
| Front | How is concentration different from strength of an acid? |
| Back | Concentration is a measure of how much acid there is in a certain volume of water, whereas strength is measured by the number of particles which ionise in water. |
| Front | Describe the structure of an atom |
| Back | The atom has a small central nucleus (made up of protons and neutrons) around which there are electrons |
