Answer 1

I think your question is -> The smallest angular momentum of electron in hydrogen atom will be

(i) h

(ii) h/2

(iii) h/2π

(iv) h/λ

answer : option (iii) h/2π

explanation : we know from Bohr's theory of atomic structure,

“ angular momentum of an electron is an integral multiple of h/2π.”

or, angular momentum of an electron in nth orbit is given as nh/2π , where n represents orbit.

the minimum value of n will be 1.

then, smallest angular momentum of electron in hydrogen atom = 1 × h/2π = h/2π

hence, option (iii) is correct choice.
