Atoms are very small. The radius of a typical atom is about 1 × 10-10 m.
The radius of a nucleus is less than a certain fraction of the radius of an atom. Give this fraction.
Calculate the largest possible radius of the nucleus of an atom of radius 1 × 10-10 m.
Give the name of the type of particle that is found outside the nucleus of an atom.
