For the 2s orbital, the value of l is zero . Hence the value of the orbital angular momentum will be zero. Therefore the correct answer is (b) zero.
According to Bohr’s theory, the angular momentum of an electron in 5th orbit is h 2.5 h π ̲ .
The angular momentum of an electron in a Bohr orbit of H – atom is 4. 2178 × 10−34 kgm2/sec .
The value of the azimuthal quantum number, l for 5d orbital is 2 .
The answer is A). The principal quantum number, or n , describes the energy lelvel in which the electron can be found, Since you’re interested in an electron located in a 5d-orbital, n=5 . The angular momentum quantum number, or l , describes the subshell, or orbital type, in which your electron is located.
S z is the z-component of spin angular momentum and m s is the spin projection quantum number. For electrons, s can only be 1/2, and m s can be either +1/2 or –1/2. Spin projection m s = +1/2 is referred to as spin up, whereas m s = −1/2 is called spin down.
Answer: It will be 2*h/2π .
Solution 2. Bohr’s second postulate states that the angular momentum of an electron has only those values that are integral multiples of h h 2 π He thought that the motion of electrons within an atom is associated with the standing wave along the orbit as shown.
The orbital angular momentum of 3p electron is √(x) h2pi .
The angular momentum (mvr) of electron in nth orbit is equal to nh/2π . Conclusion: Correct option is “d”. Note: nh/2π gives angular momentum of electron revolving in a circular orbit as proposed by Neils Bohr.
According to Bohr’s atomic model, the angular momentum of electrons orbiting around the nucleus is quantized . He further added that electrons move only in those orbits where the angular momentum of an electron is an integral multiple of h/2.

l values can be integers from 0 to n-1; ml can be integers from -l through 0 to + l. For n = 3, l = 0, 1, 2 For l = 0 ml = 0 For l = 1 ml = -1, 0, or +1 For l = 2 ml = -2, -1, 0, +1, or +2 There are 9 ml values and therefore 9 orbitals with n = 3.
Angular momentum of electron in third orbit of hydrogen atom is 3h/2pie which is equal to 1.5h/pie . Angular momentum was proposed by Neil Bohr. It gives the angular momentum of electron revolving in a circular orbit. Hence angular momentum of electron in third orbit the hydrogen is 1.5h/pie.
Thus the s, p, d, and f subshells contain 1, 3, 5, and 7 orbitals each, with values of m within the ranges 0, ±1, ±2, ±3 respectively.

∴ Possible values for ml= −2,−1,0,+1,+2 .
The angular quantum number (l) can be any integer between 0 and n – 1 . If n = 3, for example, l can be either 0, 1, or 2. The magnetic quantum number (m) can be any integer between -l and +l. If l = 2, m can be either -2, -1, 0, +1, or +2.

Traditionally, ml is defined to be the z component of the angular momentum l , and it is the eigenvalue (the quantity we expect to see over and over again), in units of ħ , of the wave function, ψ .
therefore Lx and Ly do not commute . Using functions which are simply appropriate posi- tion space components, other components of angular momentum can be shown not to commute similarly.
(a) Bohr’s quantisation condition: According to Bohr, an electron can revolve only in certain discrete, non-radiating orbits for which total angular momentum of the revolving electron is an integral multiple of h 2 π where h is the Planck’s constant.
The angular momentum vector that quantifies circular rotation of a particle about an axis is defined as the moment of the linear momentum, L = r× p , i. e. the vector product of the linear momentum and the radius vector from the point of rotation.
Answer : Bohr’s quantization condition: The angular momentum of an electron in an orbit around the hydrogen atom has to be an integral multiple of Planck’s constant divided by twice π .
The angular momentum of an electron in a Bohr’s orbit of H-atom is 4. 2178×10−34 kg m2/sec .
