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 hav a minimum
C. angular momentum must be in the direction of spin of electron
D. because electrons go ground only in horizontal orbits

Answer

A

Explanation

In the simple Bohr model, only he magnitude of angular momentum is kept qual to some integral multiple of `(h)/(2pi)`
where, h is Plancks's constant and thus, the Bohr model gives incrorect values of angular momentum
