Why electrons are removed first from 5d than 4f orbital in lanthanides?
Electrons are removed first from the 5d orbital than the 4f orbital in lanthanides because the 5d orbital has higher energy than the 4f orbital. In lanthanides, the energy difference between the 4f and 5d orbitals is small, making it more energetically favorable to remove electrons from the 5d orbital first before the 4f orbital.
Which is having the greater shielding effect 4s 4p 4d and 4f?
The 4s orbital has the greatest shielding effect because it is the closest to the nucleus and experiences less shielding from inner electrons compared to the 4p, 4d, and 4f orbitals. This means that electrons in the 4s orbital are held less tightly by the nucleus and are more easily removed.
How many nodes in 4f?
3 nodes in 4f
Would the 4f orbital or 6s orbital be closer to the nucleus?
This question is tricky because distance and location are not well defined within the electron cloud. So for the sake of explanation, let us assume that the question is "Which has a region maximum probability closest to the nucleus?" I could not find an answer in print for the 4f vs 6s. However, I did find an answer comparing the 3d and 4s. I believe that an understanding of a comparison between the 3d and 4s can be extended to a comparison between the 4f and 6s. The most probable distance of the 3d is less than the 4s. Therefore, we could extend this and say that most likely the 4f sublevel would have a distance of maximum probability closer than the 6s. You did not ask why so I will not go into an explanation.
How many 4f orbitals are in an atom?
There are seven 4f orbitals in an atom: 4f sublevel consists of seven orbitals, each designated as 4f_x, where x ranges from -3 to +3.
What are the elements of 4F series called?
The elements of the 4f series are called lanthanides. They are a group of metallic elements that have similar properties and occupy the f-block of the periodic table.
Which energy sublevel is being filled by the elements Ce to Lu?
The energy sublevel being filled by the elements Ce to Lu is the 4f sublevel. These elements are part of the lanthanide series and have their outermost electrons entering the 4f orbital.
Is 4f a valid orbital shell designation?
Yes, "4f" is a valid orbital shell designation in the electronic configuration of atoms. It represents the fourth energy level and the f subshell within that energy level.
What in the electrons are being added to the 4f orbitals?
Electrons being added to the 4f orbitals are part of the lanthanide series of elements. These elements have atomic numbers ranging from 57-71 and their electrons are filling the 4f sublevel. This filling of the 4f orbitals gives rise to the unique properties of the lanthanide elements.
What is the maximum number of electrons that can exist in 4f orbitals?
The maximum number of electrons that can exist in 4f orbitals is 14, following the principle that each orbital can hold a maximum of 2 electrons with different spins.
What does army 4f mean?

What does 4F mean in cartoons?
UNFIT FOR MILITARY DUTY - Physically, Mentally or both.
