The third shell of an atom can hold a maximum of 18 electrons. The first shell can hold up to 2 electrons, the second shell up to 8 electrons, and the third shell up to 18 electrons based on the formula 2n^2, where n is the shell number.
The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, the third energy level can hold up to 18 electrons, and the fourth energy level can hold up to 32 electrons.
The second electron shell can hold a maximum of 8 electrons.
Electron energy levels are specific regions around an atomic nucleus where electrons are likely to be found. The number of electrons that can fit into each energy level is determined by the formula 2n^2, where n denotes the principal quantum number of the energy level. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold up to 8 electrons, the third energy level (n=3) can hold up to 18 electrons, and so on.
Two electrons can fit into the first orbital shell of any atom.

The number of electrons that can fit into a particular energy level is 2n^2 (2 times n squared) where the energy level is n. So, for: energy level 1 we have 2 x (1x1) = 2, for energy level 2 we have 2 x (2x2) = 8, for energy level 3 we have 2 x (3x3) = 18. So, 2+8+18= 28 max. electrons in the first 3 energy levels.
3rd S2 P6 D10 so 18 electrons maximum
The second electron shell can hold a maximum of 8 electrons.
Inversely, 1836 electrons fit in a proton !

The inner electron shell (also known as the s shell) can hold only two electrons. There are only two elements, hydrogen and helium, whose electrons all fit into the first shell.
Oh, dude, helium only has two electrons total, so there can't be any in the third energy level. It's like trying to fit a square peg in a round hole - just not gonna happen. So, zero electrons in the third energy level of helium.
The Atom will try to acquire electrons to fit it's needs. When it acquires electrons the amount in the orbit will either (if your lucky) perfectly meet the electron orbit needs. Mostly it will be uneven (one extra). The atom will try to get rid of that/those extra electrons by bonding with a different atom that meets it's needs. This is why many atoms readily bond with others. Hope this was helpful.
