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 value of angular momentum
B. because only one of these woul 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 plank's constant and thus, The Bogr model gives incorrect value of an - gylar momentum.
