Terbium Tb
They are significant because they determine what element would be in a specific block (s,p,d,f).
Magnets can make electrons accelerate and change position through force;f= evB = -ev.Bcos(vB) + evxBsin(vB).
Remember.. I f there are more electrons than protons in an ion the charge will be negative. Here there is a -4 charge because the electrons are higher than the protons, if it were the opposite the charge would be +4.

Fluorine (F) is the most electronegative element because it has 5 electrons in it's 2p subshell. The optimal electron configuration of the 2p subshell has 6 electrons. Since F is close to this optimal configuration, electrons are highly attracted to the nucleus.
the f subshell
d subshell = 2 p subshell = 6
Maximum capacity of electrons in f-orbitals is 14, so 4f orbitals may have 1 to 14 electrons.
There are 4 electron sub-shells: s, p, d, and f. These letters stand for sharp, principal, diffuse, and fundamental, but the names are not important. s subshells have 2 electons, while p subshells have 6, d subshells have 10, and f subshells have 14. There can be higher subshells, but these subshells require too much energy to fill and no element with a g subshell (the next subshell after f) has ever been synthesized. The first shell (i.e. the first period of the periodic table) has only s. Thus, the first shell has 2 electrons. The second shell has s and p subshells, so it has 2+6 or 8 electrons. The third shell has s, p, and d subshells. It ultimately has 18 electons. This can be misleading, however. The d subshell requires more energy to fill than the higher-shell s subshell. This is why the third period of the periodic table does not have a d section: the d electron subshell of the third Bohr shell does not fill until after the s subshell of the fourth Bohr shell has filled. Looking at the periodic table, you can see that the third period only has 8 electrons, while the 4th period has 18. The 18 electrons in the fourth period are the s subshell of the fourth shell, the d subshell of the 3rd shell, and the p subshell of the 4th shell. The fourth shell is similar to the third shell, but more extreme. The fourth shell has s, p, d, and f subshells, but the f subshell is not filled until two higher s shells have been filled. It does, however, fill out to 32 electrons in the 6th period of the periodic table. In the 6th period, the first period to have 32 electrons, there are 32 electrons, filling these subshells: s subshell of the 6th shell, f subshell of the 4th shell, d subshell of the 5th shell, and then the p subshell of the 6th shell. The fifth shell would ultimately fill out to a full 50 electrons and would do so in the 8th period of the periodic table. However, as previously noted, no substance has ever been found or generated with that many electrons. It would fill the s subshell of three shells above (i.e. shell 8) before it filled the g subshell of shell 5. No element in the 8th period has ever been synthesized, so a filled fifth Bohr shell has never been found. A good example for a Bohr diagram would be Astatine, which is in the 6th period. In the first shell of the Bohr diagram, you have 2 electrons (s subshell only). It is filled completely. In the second, you have 8 electrons (s and p subshells) and in the third you have 18 electrons (s, p, and d), and both shells are filled completely. In the fourth shell, you have 32 electrons (s, p, d, and f), and it is filled completely. In the fifth shell, you have 18 electrons. This is because only the s, p, and d subshells are filled. It would require too much energy to fill the f subshell of the 5th shell, so the electrons just go to the s, p, and d subshell of higher shells. The 6th shell has 7 electrons. The 2 electrons of the s subshell are filled first, and then 5 electrons go into the p shell.
The 5p subshell is a p-subshell, and as such is filled by 6 electrons - three pairs spinning in opposite directions.The number of electrons in each subshell is as follows:Subshell s p d f theoretical next subshellsNo. of e- 2 6 10 14 18, 22, 26, etc.
The 4f subshell is being filled for the rare earth series of elements.
F for Fluorine.
A transition element of f-block Thorium has 90 electrons in natural state, it is a Radioactive element.
6th energy level can hold 72 electrons. (has s,p,d,f,g, and h subshells)
It depends which n since n is the row (period) number. 1st n = 1-s subshell, 1 orbital, and 2 electrons. 2nd n = 2-s subshell with 1 orbital and 2 electrons + 2-p subshell with 3 orbitals and 6 electrons.
There are four orbitals of the f subshell. The name of the four f subshells include 4s, 4p, 4d, and 4f. The historical name of the f subshells is called "fundamental subshells".
