The diagram shows four different locations in an atom.


A shaded circle is shown, labeled nucleus. Two small points labeled two and three are shown inside this shaded circle. A lighter shaded concentric circle is shown with a radius more than double the radius of the inner circle. A point labeled one is shown inside a section of this circle which does not overlap with the inner circle. A flower petal like shaded region is shown above and below these circles. A point labeled four is shown inside the lower petal.


Which locations are likely to have subatomic particles with the least mass?
