Available for over a year

In this episode, Dr Sunayana Bhargava and Tulela Pea define isotopes of elements and show how to calculate relative atomic mass of an elements with isotopes. Suitable for: AQA, Edexcel, OCR. For more information on isotopes, check out the BBC Bitesize website: https://www.bbc.co.uk/bitesize/guides/zwn8b82/revision/5 Key learning objectives discussed in this episode include: - Atoms of the same element can have different numbers of neutrons; these atoms are called isotopes of that element. - The relative atomic mass of an element is an average value that takes account of the abundance of the isotopes of the element. - Students should be able to calculate the relative atomic mass of an element given the percentage abundance of its isotopes.
