If the valence electrons are being added to the 4f orbitals, that means the element is lanthanides or actinides which further proves that the element is a heavy element and a member of f -block.
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.
2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10
some atoms have 5, some have none. the max is 5
The set of elements that has electrons added to the 4f sublevel as the atomic number increases are the lanthanide series elements, from cerium (Z = 58) to lutetium (Z = 71). The 4f sublevel can hold up to 14 electrons per element, hence as we move across this series, electrons are successively added to the 4f sublevel.
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.
Electrons are added to the 4f orbitals from the 5d orbitals in the lanthanide and actinide series of elements. The 4f orbitals are filled after the 5d orbitals are filled due to the overlap in energy levels, leading to the stability of the 4f electrons in these elements.
The maximum number of electrons that can exist in 4f orbitals is 14.-pg. 110 Modern Chemistry table 2:)
Maximum capacity of electrons in f-orbitals is 14, so 4f orbitals may have 1 to 14 electrons.
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.

The 4f atomic orbitals have a more complex shape compared to s and p orbitals, characterized by their angular momentum and nodes. While they can extend into regions further from the nucleus, they do have some probability density near the nucleus. However, the likelihood of finding an electron in the 4f orbitals close to the nucleus is relatively low due to their higher energy and more complex structure. Overall, the 4f orbitals do not show a high probability of finding electrons near the nucleus compared to lower energy orbitals like 1s or 2s.
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.

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.
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.
