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.
The 1st energy level can hold up to 2 electrons, the 2nd energy level can hold up to 8 electrons, and the 3rd energy level can hold up to 18 electrons.
1st energy level- 2 electrons 2nd energy level- 8 electrons 3rd energy level- 18 electrons To calculate the number of electrons other energy levels can hold, use the formula 2n^2. For example, to calculate the number of electrons the fourth level can hold, the equation would be 2(4)^2. This means that the fourth energy can hold 32 electrons. Same process for other levels.
Two valence electrons at second s- and p-level each: 2s2 2p2 The other two are nonvalence electrons on 1st s-level: 1s2
Helium has only two electrons. Both the electrons are arranged in the 1st energy level or 1s orbital.
It depends which n since n is the row (period) number. 1st n = 1-s subshell, 1 orbital, and 2 electrons. 2nd n = 2-s subshell with 1 orbital and 2 electrons + 2-p subshell with 3 orbitals and 6 electrons.

Argon has a total of 18 electrons. There are 2, 8 and 8 electrons in the 1st, 2nd and 3rd energy levels respectively.
Sodium (11Na) has 2 electrons in the first (1st), 8 electrons in the second (2nd) and one in the (3rd) level.
1st-22nd- 83rd- 184th- 32
The 1st energy level can hold up to 2 electrons, the 2nd energy level can hold up to 8 electrons, and the 3rd energy level can hold up to 18 electrons.
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
All elements except hydrogen have two electrons in the first energy level.
K (potassium) has 2 electrons the the 1st energy level, 8 each in the 2nd and 3rd, and 1 electron in the 4th.
The answer to this depends on the energy level under consideration.In general, the maximum number of electrons occupied in one energy level is given by 2n2where n is the number of energy level. Thus 1st, 2nd, 3rd and 4th energy levels can occupy a maximum of 2, 8, 18 and 32 electrons

1st level: 2 2nd level : 8 3rd level : 18
In the second energy level of an atom, there can be a maximum of 8 electrons. Silicon has 14 electrons in total, with 2 in the first energy level and the remaining 12 electrons would be in the second energy level.
