Question
Use the exact values you enter in previous answer(s) to make later calculation(s). Previous question and values----->>>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? =_____________m3 (c) What fraction of a hydrogen atom is occupied by the nucleus? =_____________Explanation / Answer
volume = (4/3)Pi r^3 proton volume = (4/3)Pi(1 x 10 -15m)^3 = 4 x 10^-45 m^3 atom volume = (4/3)Pi(1 x 10 -10m)^3 = 4 x 10^ -30 m^3 fraction occupied by nucleus 1:10^15 one in 1 00000 00000 00000 is occupied by the nucleus so those drawings we see of atoms greatly exaggerate the size of the nucleus
