Which set of quantum numbers is unacceptable?

The quantum number n is an integer, but the quantum number ℓ must be less than n, which it is not. Thus, this is not an allowed set of quantum numbers. The principal quantum number n is an integer, but ℓ is not allowed to be negative. Therefore this is not an allowed set of quantum numbers.

Which quantum no does not follow from?

Spin quantum number does not follow from the solutions of Schrodinger wave equation.

What are the 4 quantum numbers and what is their significance?

In atoms, there are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).

Which Subshell is not permissible?

Correct Option A 2d Explanation:As per the quantum theory of the atomic structure the subshells are equal to the value of principal quantum number i.e. if n = 1 there will be only one subshell if n = 2 there will be two subshells i.e. s and p. Hence there cannot be subshell by name 2d.

Which of the following orbitals Cannot exist?

2d and 3f orbitals cannot exist. The n=2 shell consists only of s and p subshells. The n=3 shell consists only of s,p, and d subshells.

Which of the following is not possible for any of the four quantum numbers?

In the option (C), n=4,l=1 represents 4p but m=−2 is not possible as the values of m for 4p must vary between -1 to +1.

Which would be an invalid listing within an electron configuration?

Which would be an invalid listing within an electron configuration? There are no 2d orbitals, so even though 5 is an acceptable number for d occupancy, this listing can not exist in an electron configuration.

Which of the following quantum number Cannot be deducted from Schrodinger?

spin quantum number
The quantum number not obtained from the Schrodinger’s wave equation is spin quantum number ‘s’.

What does the spin quantum number determine?

The Spin Quantum Number (ms) describes the angular momentum of an electron. An electron spins around an axis and has both angular momentum and orbital angular momentum. Because angular momentum is a vector, the Spin Quantum Number (s) has both a magnitude (1/2) and direction (+ or -).

What is the significance of azimuthal quantum number?

Azimuthal Quantum Number is a quantum number for atomic orbitals which helps identify their orbital angular momentum. They define the shape of the orbital. Azimuthal quantum number is the second set of quantum numbers, and is very helpful in determining the unique set of an electron’s quantum state.

Which of the following quantum numbers is not used for gaining knowledge about orbitals?

Answer and Explanation: For a given value of the Azimuthal quantum number l, there can be (2l+1) values of the magnetic orbital momentum quantum number ml that range from -l t +l. Thus, for l = 2, the possible values of ml are -2, -1, 0, +1, +2. Thus, the set in option (c) is not correct.
