Which are the four quantum numbers for an electron present in 4f orbital?

The correct answer is n = 4, I = 3, m = +1, s = +1/2.Key Points

• The four quantum numbers for an electron present in 4f orbital are n = 4, l = 3, m = +1, and s = +1/2.
• The principal quantum number (n) indicates the energy level of the electron, and for 4f orbital, it is 4.
• The azimuthal quantum number (l) determines the shape of the orbital, and for f orbital, it can have values from 0 to n-1, which gives l = 3.
• The magnetic quantum number (m) specifies the orientation of the orbital in space and can have values from -l to +l, which gives m = +1 for the 4f orbital.
• The spin quantum number (s) describes the intrinsic angular momentum of the electron and can have two values, +1/2 or -1/2, for the electron in 4f orbital, it is +1/2.

Additional Information

• Quantum Numbers are a set of numbers that describe the properties of an electron in an atom, including its energy level, orbital shape, orientation, and spin.
• The characteristics of atomic orbitals and the electrons within them are described by quantum numbers.
• There are four quantum numbers that represent the states of an electron in an atom or an ion.
