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 of 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 greatest mass?
1 and 2
2 and 3
1 and 4
