Question:

Obtain an expression for the most probable radias at which an electron will found when it occupies the hydrogen 1s orbital.

Bohr Radius

The Bohr radius is the average distance of an electron from the nucleus of a hydrogen atom. Niels Bohr originally computed it by making the assumption that electrons orbit only at certain radii from the nucleus, and this radius corresponds to the lowest energy line present in the hydrogen spectrum. Though his theory was incorrect and failed to predict accurately for atoms larger than hydrogen, his result for hydrogen is still important today. It is a fundamental physical constant and is used as a unit in atomic physics.

Answer and Explanation:

The formula for the Bohr radius is:

{eq}a_0 = \dfrac{\hbar^2}{m_e e^2} {/eq}

where {eq}\hbar {/eq} is the Planck constant divided by...
