Chemistry Question on Structure of atom

Azimuthal quantum number defines

A

e/m ratio of electron

B

angular momentum of electron

C

spin of electron

D

magnetic momentum of electron

Answer

angular momentum of electron

Explanation

Solution

Azimuthal quantum number defines the spatial distribution of electron cloud and angular mementum. e.g. l=0,    s−l=0,\,\,\,\, s - sub sehll    l=1,        p−\,\,\,l =1, \,\,\,\,\,\,\,\,p - sub shell    l=2,       d−\,\,\,l =2, \,\,\,\,\,\,\,d - sub shell Orbital angular momentum of an electron is calculated using the expression. =l(l+1)h2π=\sqrt{l(l+1)} \frac{h}{2 \pi}
