In general, when the transition metals lose electrons, the s shell electrons are lost before the d shell electrons. This is because the s electrons are higher in energy when the atom is in its ionized state. For example, in elements like iron (Fe), the 4s electrons are lost first, followed by the 3d electrons. This trend is observed across the Periodic Table, particularly in transition metals.

What a maximum of eight electrons can occupy the first shell?

Why does an element lose 4S electrons before 3D electrons?
An element loses 4s electrons before 3d electrons because the 4s orbital has a higher energy level (n value) than the 3d orbital. When an atom loses electrons to form a cation, it tends to lose the electrons from the outermost shell first, which in this case is the 4s orbital.
What is the Electron confirguartion of Iron?
Iron has 26 electrons in total. the first electron shell has 2 electrons, the second electron shell has 8 electrons, the third electron shell has 14 electrons and the final shell of iron(Fe) has 2 electrons.
Which orbital is rhodium's last electron in?
If you are filling in the electrons it will be in the 4d orbital. If you are removing electrons the first to come out is in the 5s electrons since transition metals lose 's' electrons before 'd' electrons
How many electrons would make the d shell complete?
The d shell needs 10 electrons to be complete.
How many electrons does Magnesium need to complete last shell?
Magnesium, in the second group, can either gain six electrons or lose two electrons to achieve a full outer shell.

How many electrons fit in the 3rd shell?
The third shell, also known as the M shell, can hold a maximum of 18 electrons. This shell consists of 3 subshells: s, p, and d. The s subshell can hold up to 2 electrons, the p subshell can hold up to 6 electrons, and the d subshell can hold up to 10 electrons.
Why does an element lose 4S electrons before 3D electrons?
An element loses 4s electrons before 3d electrons because the 4s orbital has a higher energy level (n value) than the 3d orbital. When an atom loses electrons to form a cation, it tends to lose the electrons from the outermost shell first, which in this case is the 4s orbital.
In a Bohr diagram how many electrons are in each shell?
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.

Do main group metals from period 5 onward tend to lose electrons from the d subshell first?
Yes, main group metals from period 5 onward tend to lose electrons from the s subshell first before losing electrons from the d subshell. This is because the s subshell has lower energy levels compared to the d subshell, making it easier for the electrons to be lost from the s subshell.
How many electrons go in the first second and third orbitals?
Two (2) electrons (s shell)Eight (8) electrons (2 in s, 6 in p)Eighteen (18) electrons (2 in s, 6 in p, 10 in d)The periodic table PDF at Los Alamos National Laboratory is pretty good and has the shell configurations. See related link.
