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.
Two. If you move onto the second, it can contain eight and the third can contain eight.

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.
Each inner energy level of an atom can hold a maximum number of electrons. Electrons orbit around the nucleus of an atom in shells. Each shell has a set maximum number of electrons it can hold, and the shell has to be completely filled before electrons can start filling up the next shell.
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.

The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
K (potassium) has 2 electrons the the 1st energy level, 8 each in the 2nd and 3rd, and 1 electron in the 4th.
Sodium (11Na) has 2 electrons in the first (1st), 8 electrons in the second (2nd) and one in the (3rd) level.
All elements except hydrogen have two electrons in the first energy level.
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

Argon has a total of 18 electrons. There are 2, 8 and 8 electrons in the 1st, 2nd and 3rd energy levels respectively.

The first energy level can hold 2. The second level can hold 8. The third level can hold 18. Fourth and beyond can hold 32.
