Question

12.The angular momentum of an electron in H atom is (2h)/(pi) .The electron belongs to I l 1) 1^( st ) orbit 2) 2^( nd ) orbit 3) 3^( rd ) orbit 4) 4^( th ) orbit

Answer 1

Answer:

4 rth orbit

explanation:

The angular momentum of the electron in the nth orbit of hydrogen is

The angular momentum of the electron in the nth orbit of hydrogen is nh/2π=2h/π

The angular momentum of the electron in the nth orbit of hydrogen is nh/2π=2h/π∴n=4

#SPJ2

Answer 2

ANSWER : THE ANGULAR MOMENTUM OF THE ELECTRON IN Nth ORBIT OF HYDROGEN IS NH/2π

EXPLANATION : send the 2 from denominator to numerator !!

so we get,

2h/π. then,

The angular momentum of the electron in the nth orbit of H atom is NH/2π

=2h/π

therefore , n=4
