Explain that almost all the mass of an atom is concentrated in the nucleus.

In the subtopic Size and mass of atoms, this learning objective focuses on explain that almost all the mass of an atom is concentrated in the nucleus. It sits within A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes for AQA GCSE Chemistry 8462, so the explanation must keep the chemistry linked to Size and mass of atoms rather than drifting into a nearby idea. Approved keywords to use include that, almost, mass, atom, concentrated. mass means the amount of matter in an atom, primarily found in the nucleus Avoid the mistake of students often think that the mass of an atom is evenly distributed throughout the atom rather than concentrated in the nucleus; instead, emphasize that almost all the mass of an atom is located in the nucleus, which contains protons and neutrons, while electrons contribute very little to the overall mass For exam answers, remember that almost all the mass of an atom is concentrated in the nucleus, so prioritize understanding its structure and components
