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.
What is the highest sublevel electrons in the element Promethium an f block element occupy?
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
What is the maximum number of electrons each of the following can hold... 2s 5p 4f 3d 4d?
2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10
What is the maximum number of electrons that can occupy the n equals 4 energy level?
there are 16 orbitals in a n=4 shell *since there are 2 electrons in each orbital, that makes 32 electrons total here
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.

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 the highest sublevel electrons in the element Promethium an f block element occupy?
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
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.-pg. 110 Modern Chemistry table 2:)
What is the maximum number of electrons each of the following can hold... 2s 5p 4f 3d 4d?
2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10

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.
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 electrons can occupy the 4f sublevel?
The elements in period 4 that have electrons in the 3d sublevel are elements 21 - 36. Refer to the Related Links for a printable periodic table that includes electron configurations.
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.
according to the Aufbau principle, what orbital is filled after the 6s orbital?
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.
