Explanation Given info: The diameter of nucleus of hydrogen atom is 7.3 cm , the fraction of volume occupied by nucleus in hydrogen atom is 8.39 × 10 − 16 ( from problem 1PCE). The formula to calculate radius of nucleus of hydrogen atom is, r = d 2 Here, r is the radius of nucleus. d is the diameter of nucleus. Substitute 7.3 cm for d in the above equation to find r . r = 7.3 cm 2 = 3.65 cm ( = 3.65 × 10 − 2 m ) The formula to calculate volume of sphere is, V = 4 3 π r 3 Here, V is the volume of sphere. r is the radius of sphere. The formula to calculate radius of hydrogen atom is, Fraction of volume occupied by nucleus = Volume of nucleus Volume of atom Substitute 8

Quantum mechanics and hydrogen atom

Consider an electron of mass m moves with the velocity v in a hydrogen atom. If an electron is at a distance r from the proton, then the potential energy function of the electron can be written as follows:

Isotopes of Hydrogen Atoms

To understand isotopes, it's easiest to learn the simplest system. Hydrogen, the most basic nucleus, has received a great deal of attention. Several of the results seen in more complex nuclei can be seen in hydrogen isotopes. An isotope is a nucleus of t…

Students have asked these similar questions

The nucleus of a hydrogen atom is a single proton, which has a radius of about 1.1 x 10-15 m. The single electron in a hydrogen atom orbits the nucleus at a distance of 5.3× 1011 m. What is the ratio of the density of the hydrogen nucleus to the density of the complete hydrogen atom? Number i | Units (no units)

It may be argued on theoretical grounds that the radius of the hydrogen atom should depend only on the fundamental constants h, e, the electrostatic force constant k = 1/4πℰ0, and m (the electron’s mass). Use dimensional analysis to show that the combination of these factors that yields a result with dimensions of length is h2kme2.
