no. of electrons to fill an energy level = 2n2.
= 2x32 = 18
The third energy level can hold a maximum of 18 electrons.
Nitrogen has five electrons in its outermost energy level (the second shell), which can hold a maximum of eight electrons. To achieve a stable octet configuration, nitrogen requires three additional electrons. Thus, three additional electrons are needed to fill its outermost energy level.
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
The second energy level can hold a maximum of 8 electrons. Magnesium has 12 electrons, so in its second energy level, there will be 8 electrons (2 in the first energy level and 8 in the second energy level).
valence electrons are the electrons in the outermost energy level
The third energy level can hold a maximum of 18 electrons.

Completely filled octet.

undiscovered...yet, but there are a few...go forward 50 years and see
The fourth energy level can hold a maximum of 32 electrons. This level consists of 4 sublevels (s, p, d, f), which can hold a total of 32 electrons when completely filled according to the Aufbau principle.
More energy have the electrons in the second level of energy.
it is called complete or completely stable
Completely filled octet.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
2n^2 = 18 therefore n^2 = 9 therefore n = 3
If the atom is chemically stable it doesnt need to bond, it is chemically stable when the outermost level is completely full of electrons
