The nucleus of a hydrogen atom is a single proton. The radius of a proton is approximately 1 fm (1 multiplied by 10âˆ'15 m).
(a) What is the approximate volume of a proton?
m3
(b) A hydrogen atom has an approximate radius of 5 multiplied by 10âˆ'11 m (called the Bohr radius). What is the approximate volume of a hydrogen atom?
(c) What fraction of a hydrogen atom is occupied by the nucleus?
