(a) Explanation Write the expression for the orbital speed of the electron. v 1 = k e e 2 m e r 1 (I) Here, v 1 is the orbital speed of the electron, k e is the Lorentz constant, e is the charge of the electron, m e is the mass of the electron, r 1 is the radius of the first orbit in the hydrogen atom. Write the general expression for the radius of any orbit in the hydrogen atom. r n = n 2 a 0 (II) Here, r n is the radius of the n t h orbit, a 0 is the Bohr radius. Conclusion: Substitute 1 for n and 5.29 × 10 − 11 m for a 0 in equation (II) to find r 1 . r 1 = ( 1 ) 2 ( 5 (b) To determine The kinetic energy of the electron. (c) To determine The electric potential energy of the atom.

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…

Mass of Hydrogen Atom

Hydrogen is one of the most fundamental elements on Earth which is colorless, odorless, and a flammable chemical substance. The representation of hydrogen in the periodic table is H. It is mostly found as a diatomic molecule as water H2O on earth. It is …
