1st level : 2
2nd level : 8
3rd level : 18
4th level : 32
You can figure it out by the formula 2n^2 (2 times n squared) where n is the energy level.
So, level 5 is 2 (5x5) = 50.
The above is the maximum number, not necessarily the number in each energy level in any given element, because an element does not necessarily fill an entire energy level before moving on to the next one.
An argon atom has 2 electrons in its first energy level, 8 electrons in its second energy level, and 8 electrons in its third energy level.
Argon has a total of 18 electrons. There are 2, 8 and 8 electrons in the 1st, 2nd and 3rd energy levels respectively.
Maximum of 2n2, where n is the energy level.
The number of electrons in each energy level is determined by the formula 2n², where "n" is 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 a maximum of 8 electrons, and so on.
K (potassium) has 2 electrons the the 1st energy level, 8 each in the 2nd and 3rd, and 1 electron in the 4th.

K (potassium) has 2 electrons the the 1st energy level, 8 each in the 2nd and 3rd, and 1 electron in the 4th.
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
The second energy level of atoms can hold a maximum of 8 electrons.
In a neon atom, the first energy level or orbit can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons. Therefore, a neon atom would have 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level, totaling 18 electrons.
In a barium atom, there are 2 electrons in the first energy level, 8 electrons in the second energy level, 18 electrons in the third energy level, 18 electrons in the fourth energy level, 8 electrons in the fifth energy level, and 2 electrons in the sixth energy level.
