For he ground state , the electron int eh H-atom has an angular momentum `=h`, accord-ing to the simple Bohr model. Angular momentum is a vector ans hence there will be infi-nitely many orbits with the vector pointing in alll possible direction . In actuality , this is not true,

Options

A. Because Bohr model gives incorrect values of angular momentum
B. Because only one of these would have a minimum energy
C. Angular momentum must be in the direction of spin of electron
D. Because electrons go around only in horizontal orbits

Answer

A

Explanation

In the simple Bohr model, only the magnitude of angular momentum is kept equal to some integral multiple of `(h)/(2pi)`, where, h is Planck’s constant and thus, the Bohr model gives incorrect values of angular momentum.
