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

Simple Bohr model, infact does not give correct values of angular momentum of revolving electrons. It gives only the magnitude of angular momentum, which is a vector. So the given statement in the question is not true. Choice (a) is correct.
