Hi,
In the OCR Chemistry A spec it says:
"Trends in ionisation energy support the Bohr model of the atom"
I understand that ionisation energy is a measure of how easily an atom loses electrons to form positive electrons and I know that the Bohr model is the current model of the atom.
I don't understand is what the specification requires me to know and how to relate these?

The Bohr model is not the current model of the atom. It's an early quantum mechanical model that began to explain that electrons can only sit in certain energy levels. The tables of successive ionisation energies show large gaps where these energy levels differ, if there were no 'shells' then the large gaps wouldn't exist - there would be a smooth pattern (presumably).

Things in the Additional Guidance column starting with HSW and a number from 1-12 are not things learners need to worry about, they are there to please the Department for Education and are used by the exam creation process to please the DfE.
