If an electron is confined to a region of size 43.0 nm, what is the minimum possible uncertainty in its momentum? 1.22E-27 kg * m/s The nucleus of a hydrogen atom is a single proton. The radius of a proton is approximately 1 fm (1E?15 m).
(a) What is the approximate volume of a proton?
=_____________m3
(b) A hydrogen atom has an approximate radius of 5E?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?
=_____________
