Electrons orbiting an atomic nucleus do not do so like planets round the sun, they do so in shells round the nucleus.
Each electron shell can accommodate 2n2 electrons, i.e. the first shell can accommodate 2 electrons, the second shell 8 electrons, the third shell 18 electrons, etc.
Electrons always fill the smallest shells (nearest the nucleus) first as this is the lowest energy configuration.
The shells do not have to be full - for instance a hydrogen atom has just one electron and thus the first shell has only one electron in it not two.
It is possible to push an inner electron up into a higher shell (by providing energy) if there is a vacancy - however it will fall back and when it does so it will emit a photon of light this is why things glow when they get hot.
Every orbital is different. 2 can occupy the first orbital then 8 can occupy mostly the rest. When you start getting really low on the periodic table orbitals start holding 16, but not till u get really low
The number of electrons that can occupy each shell in an atom is determined by the formula 2n2, where n is the shell number.
The number of electrons per orbit in an atom is determined by the energy level of the orbit. Each orbit can hold a maximum number of electrons, with the first orbit holding up to 2 electrons, the second holding up to 8 electrons, the third holding up to 18 electrons, and so on.
Carbon has 4 electrons on its second shell. This is calculated based on the maximum number of electrons that can occupy the second shell, which is 8.
Neon has 8 electrons in its outermost orbit. The outermost orbit, also known as the valence shell, can hold a maximum of 8 electrons. Neon is a noble gas and has a full valence shell, making it stable and unreactive.

The second orbit has 8 electrons.
Nitrogen has 7 electrons orbiting its nucleus in a neutral state. Two electrons occupy the first shell, while the remaining five electrons are distributed in the second shell.
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
13 electrons are in the third orbit of Manganese.
The electrons in beryllium occupy a total of four orbitals. Beryllium has 4 electrons, which fill the 1s, 2s, and 2p orbitals.

In a lead atom, the number of electrons in each orbit are as follows: 2 electrons in the first orbit (closest to the nucleus) 8 electrons in the second orbit 18 electrons in the third orbit 32 electrons in the fourth orbit

A total of 82 electrons
Only 2 electrons can reside in the innermost shell.
