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.

In a Bohr-Rutherford diagram of a silicon atom how many electrons fill each electron shell?
well the first shell can only contain 2 electrons then in the second shell and up you can have up to eight that is how it goes
What is the Bohr diagram of the compound of lead chloride?
The Bohr diagram for lead chloride (PbCl2) would show lead with two electrons in its outer shell and chlorine atoms with seven electrons each, forming a stable ionic bond. Lead would have a full inner shell and an empty outer shell, while the chlorine atoms would each have a complete outer shell.
How many protons belong in each shell of a diagram for the element seaborgium?

What does the bohr diagram for carbon look like?
I assume you mean Bohr, as in Neils Bohr, the physicist and chemist famous for the Bohr model of the atom.Imagine a "C" inside of a square. If one were to put one "dot" on each side of the hypothetical box, you would have a bohr model Carbon atom.
What diagram represents an atom and its electrons?
A Bohr model diagram is commonly used to represent an atom and its electrons. This model shows the electrons orbiting around the nucleus in specific energy levels or shells. Each shell can hold a certain maximum number of electrons based on the atomic number of the atom.

How many orbitals would the Bohr diagram for aluminum have?
The Bohr diagram for aluminum would have three orbitals, as aluminum has three electron shells (K, L, M). Each shell corresponds to an orbital level in the Bohr model.

A Bohr model diagram is commonly used to represent an atom and its electrons. This model shows the electrons orbiting around the nucleus in specific energy levels or shells. Each shell can hold a certain maximum number of electrons based on the atomic number of the atom.
Why does the M shell in Bohr theory really contain 18 electrons while the N shell really contains 32 electrons?
The formula for getting the total number electrons occupying a shell is given by 2n2 For M shell the principal quantum number, that is, 'n' is 3. So 2 x 9 = 18 For N shell its quantum number is 4 and hence 32 electrons.
What is the tin bohr model?
The bohr model of an atom shows the number of electrons, neutrons, and protons contained in the atom. Each electron is in an orbital (the lines), and the protons and neutrons are contained in the nucleus (the center thingy).
What is th bhor model for beryllium?
The Bohr model for beryllium is a simplified representation of a beryllium atom where electrons orbit the nucleus in circular orbits at specific energy levels. In this model, beryllium has four electrons arranged in two energy levels or shells, with two electrons in the inner shell and two in the outer shell. The Bohr model helps to explain the electronic structure and properties of beryllium.
What is the Bohr-Rutherford diagram?
The number of protons that an atom of an element has can be found in the periodic table by finding the ATOMIC NUMBER (the smaller number). Therefore, we can also find the number of electrons.got it?
How does a Bohr diagram look like?
A Bohr diagram is a simple representation of an atom, showing the nucleus in the center with electrons in specific energy levels or shells surrounding it. Each shell is labeled with the number of electrons it can hold, and electrons are represented by dots or other symbols on the shells.
How do you determin a atomic number in a bohr diagram?
The number associated with positive charges in a nucleus of each atom determine the atomic number in a Bohr diagram.
