Download Solution PDFConcept:
The mathematical expression for the angular momentum of an electron can be stated as follows:
nh2π
�h2π �h2π
Here, m = mass of electron
v = velocity of electron
r = radius of the orbit or shell in which the electron is revolving/rotating
n = number of orbit in which the electron is revolving
h = Planck’s constant having a value of
Explanation:
Electron is excited from n=1 to n=3 i.e. from K to M shell,
Hence, the correct answer is
