The 'size' by thef an atom is sometimes considered to be measured by density of the radius of a sphere that contains 90 per cent of the charge density of the electrons in the outermost occupied orbital. Calculate the 'size' of a hydrogen atom in its ground state according to this definition. Go on to explore how the 'size' varies as the definition is changed to other precentages, and plot your conclusion.
