Show that the circumference of the Bohr orbit for the hydrogen atom is an integral multiple of the de Broglie wave length associated with the electron revolving arround the nucleus.

Calculate the uncertainty in position of an electron, if Δv = 0.1% and \(\upsilon \) = 2.2 x 10⁶ ms^-1.

The quantum mechanical treatment of the hydrogen atom gives the energy value:
\({ E }_{ n }=\frac { -13.6 }{ { n }_{ 2 } } ev{ \ atom }^{ -1 }\)
