The first shell can hold two, the second and beyond can hold 8.
An atom with 16 electrons would have 3 electron shells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 8 electrons.
There are 1 electron in the third shell of lithium. Lithium has an atomic number of 3, so it has 3 electrons in total. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons, leaving 1 electron in the third shell.

Germanium has four electron shells. Its electron configuration is [Ar] 3d10 4s2 4p2, indicating it has electrons in the first four energy levels (shells). The first shell can hold up to 2 electrons, the second up to 8, the third up to 18, and the fourth shell holds the remaining electrons.
The second shell of an atom has two sub-shells: the 2s and 2p sub-shells. The 2s sub-shell can hold a maximum of 2 electrons, while the 2p sub-shell can hold a maximum of 6 electrons, allowing the second shell to accommodate a total of 8 electrons.
The second electron shell can hold a maximum of 8 electrons.
There are 8 electrons in an O shell. The O shell is the second energy level in an atom, and it can hold a maximum of 8 electrons.
An atom with 16 electrons would have 3 electron shells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 8 electrons.
Sodium has two electron shells: the first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons. Sodium has 11 electrons in total, with 2 in the first shell and 8 in the second shell.
There are 2 electron shells around the nucleus of a beryllium atom. The first shell can hold a maximum of 2 electrons, and the second shell can hold a maximum of 8 electrons. Since beryllium has 4 electrons, 2 electrons will be in the first shell and the remaining 2 electrons will be in the second shell.
The third electron shell can hold a maximum of 18 electrons.
A fluorine atom has 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons, giving a total of 10 electrons for a fluorine atom.
Sodium has two inner shells. The first inner shell can hold up to 2 electrons, while the second inner shell can hold up to 8 electrons. Sodium's electron configuration is 2-8-1, with one electron in the outermost shell.
I think the answer for the 2nd principle energy level is 8 electrons
The first shell can have 2 electrons, the second shell has 8 electrons and the third shell has 8 electron also. No matter what, electron fill up the first shell and then move into the next shell and then the next one. To answer the question, the first shell would have 2 electron and then the second shell would have six.
An atom with 10 electrons will have 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons.
Sulfur has six electrons in its third electron shell.
