# Readers ask: what set of quantum numbers could correspond to a 4f orbital?

For a 4f orbital, the Principal quantum number is n = 4, the azimuthal quantum number is 3. The values ​​of the magnetic quantum numbers are -3, -2, -1, 0, +1, +2, +3. A total of 7 orbitals are present in the 4f subshell.

## Is 4f possible?

with f subshell, l=3 so ml =-3,-2, -1, 0,+1,+2,+3 so there are seven possible values ​​of ml. Remember that 4 is the number of principal quantum number, which has nothing to do with the number of orbitals. So there are seven 4f orbitals.

## What is a 4f orbital?

4f orbitals are the seven f orbitals of the 4thth Electron shell (energy level). 4f orbitals are the first subset of f orbitals. That means 1St2nd and 3approx Electron shells do not have f orbitals.

## Which of the following sets of quantum numbers refers to a 4d orbital?

For a 4d orbital, the value of n (principal quantum number) is always 4 and the value of l (azimuthal quantum number) is always 2. The values ​​of the magnetic quantum number thus range from -l to l The possible values ​​of ml for the 4d orbital are -2, -1, 0, 1 and 2.

## What is the quantum number of 4f?

For a 4f orbital, the principal quantum number is n = 4, the azimuthal quantum number is 3. The values ​​of the magnetic quantum numbers are -3, -2, -1, 0, +1, +2, +3. A total of 7 orbitals are present in the 4f subshell. Each orbital can contain two electrons present in opposite directions.

## How many orbitals are in 4f?

There are seven 4f orbitals for each atom. The f orbitals are unusual in that there are two sets of orbitals that are commonly used.

## Where does 4f begin?

Period 6 begins with elements whose last added electron is in the 6s sublevel. The next step is where period 6 differs from period 5. Look again at Figure 5.8 and notice that the 4f sublevel is filled after the 6s sublevel and before the 5d sublevel.

## Are 4f and 5f orbitals equally shielded?

4f and 5f orbitals are equally shielded.

4, 2, 1, -1/2.

## Which of the following sets of quantum numbers can a 4s electron describe?

For a 4s electron, the number 4 stands for n while s stands for ℓ. l corresponds to the following values: s = 0, p = 1, d = 2, f = 3; this means that in this orbital ℓ = 0. The value for mℓ must be between -ℓ and ℓ, so if ℓ = 0, mℓ must also be 0.

## How many electrons does 4f contain?

The 4p orbital contains 6 electrons. There is a 10 electron 4d orbital that coincides with the 5th energy level of the periodic table. There is also a 4f orbital with 14 electrons, but this coincides with the 6th energy level of the periodic table.

## Which of the following orbitals has the four lobes on the axis?

the d orbitals have (i) four lobes and two nodes (ii) four lobes. Hybridization of these atomic orbitals forms a square planar complex [ AIEEE 202] a)s, px, p
