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.
How many node are present in 4f orbital?
There are 3 nodes present in a 4f orbital: one radial node and two angular nodes. This means that there are regions in the orbital where the probability of finding an electron is zero.
Which orbitals are characteristics of the lanthanide elements?
The 4f orbitals are the characteristic orbitals of lanthanide elements. These orbitals are involved in lanthanide chemistry and contribute to their unique chemical properties and behavior. The 4f orbitals are part of the inner electron shell in lanthanides.
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.
How many types of orbitals are in the sixth shell?
There are four types of orbitals in the sixth shell: s, p, d, and f orbitals. The s orbital is spherical, the p orbitals are dumbbell-shaped, the d orbitals are cloverleaf-shaped, and the f orbitals have more complex shapes. Each type of orbital can hold a specific number of electrons.
according to the Aufbau principle, what orbital is filled after the 6s orbital?
4f orbital

Why does one electron in a rubidium atom occupy a 5s orbital rather than a 4d or 4f orbital?
The 5s orbital has a lower energy level than the 4d or 4f orbitals in a rubidium atom, according to the aufbau principle. Electrons fill orbitals starting from the lowest energy level to the highest energy level. This is why the electron fills the 5s orbital before the 4d or 4f orbitals in a rubidium atom.

What is an invalid orbital designation 4p 3s 2d 5f?
The orbital designation "4p 3s 2d 5f" is invalid because it does not follow the proper order of filling orbitals according to the Aufbau principle. The correct order is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p.
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.
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.
What is the maximum number of electrons in 3f?
3f can not exist by the Aufbau principle, quantum mechanics and Hunds rules. In level one there is only 1s In level 2 there is 2s and 2p In level 3 there is 3s, 3p and 3d Only in level 4 and beyond is there an f shell. In level 4 there is 4s, 4p, 4d and 4f. The 4f can hold up to 14 electrons.
What is the electronic structure of neodymium?
The electronic structure of neodymium (Nd) is [Xe] 4f4 6s2. This means it has 4 electrons in the 4f orbital and 2 electrons in the 6s orbital.
