The first 5f subshell first gets full at element 89, which is actinium.
It is not possible to have a 5f orbital as it is not part of the main energy level orbitals (s, p, d). The order is typically s, p, d, f.
The actinides family corresponds to the 5f subshell. This subshell can hold a maximum of 14 electrons and is located in the seventh period of the periodic table. The actinides are a series of elements with atomic numbers 89 to 103.
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p
The electron configuration of mendelevium is [Rn]5f137s2.
A 5f
e = 5f f = e/5
5F stands for 5 Francs, the currency of France before the conversion to the Euro.
The 5f sublevel can contain a maximum of 14 electrons.
It then is: 5f
5f
3 x -5f equal help please and explain = -2
The 7s subshell has less energy than the 5f subshell due to its position in the periodic table and the principles of electron shielding and penetration. The 5f orbitals are more diffuse and experience greater shielding effects from inner electrons, leading to increased energy levels. Additionally, the effective nuclear charge felt by electrons in the 5f subshell is lower than that in the 7s subshell, which contributes to the higher energy of 5f electrons. Thus, the 5f orbitals are higher in energy compared to the more compact 7s orbitals.
Firstly your english is terrible. And the average height is 5f to 5f 2"

If: 5f+3 = 28 then f = 5 because (5*5)+3 = 28
