The third shell can hold a maximum of 18 electrons. It has three subshells - 3s, 3p, and 3d - which can accommodate a total of 18 electrons.
It is because the two electrons in helium are placed in K-shell. The K-shell has the capacity of only two electrons. Therefore, in Lithium the third electron is placed in the L-shell. You can find the capacity of a shell to hold electrons by the formula 2n2 where n is the shell no.
The innermost shell can accomade 2 electrons
First shell has 2 electrons. Next shell has 8 electrons. The third shell has 18 but scientist say 8 so they don't confuse graphs.
8. But if it is the first shell it can only be 2.
It depends what electronic state it's found in, but in it's ground state (natural form) it has two electrons in the first shell, eight in the second and none in the third. This is because it has an atomic number of 10. 2+8 = 10.
Third Shell
k shell has two electrons because in the structure of an atom every shell has an capacity to have fixed number of electrons that why k shell has capacity to have 2 electrons.
It is because the two electrons in helium are placed in K-shell. The K-shell has the capacity of only two electrons. Therefore, in Lithium the third electron is placed in the L-shell. You can find the capacity of a shell to hold electrons by the formula 2n2 where n is the shell no.
Sulfur has six electrons in its third electron shell.
The third last shell. What a mouthful!
The innermost shell can accomade 2 electrons
It is sodium Chlorine is the first element that needs a third shell.
The third electron shell has a maximum capacity of 18 electrons. This shell consists of 1 s orbital, 3 p orbitals, and 5 d orbitals, accommodating a total of 18 electrons according to the Aufbau principle and the Pauli exclusion principle.
First shell has 2 electrons. Next shell has 8 electrons. The third shell has 18 but scientist say 8 so they don't confuse graphs.
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
