Want this question answered?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
Sort of but not exactly.A neutral isolated atom of boron has, nominally, three occupied electronic energy levels (1s, 2s, and 2p).However, it has an infinite number of unoccupied energy levels (as do all atoms).Also, in compounds, there's a strong tendency for the 2s and 2p orbitals to "hybridize", forming sp, sp2, or sp3 orbitals, each of which has its own characteristic energy level.Boron does not have three energy levels. If you know the element's principle quantum number, then you can find how many electrons can fit in an atom of a specific element. In this case, Boron can only store 2p1/2 (p is the principle quantum number) electrons. This is getting too complex, and isn't required for you to know as of this exact moment. The answer is that Boron only has two energy levels.
Generally, 8 or less electrons may only inhabit the second ring.
It is because when you move down, the number of electrons increases. When the number of electrons increases, it calls for more energy levels to fit these electrons.With each additional period, an additional energy level is occupied. This additional energy level is farther from the nucleus than the previous energy level, so the atoms increase in size.
It is all to do with the Aufbau and Pauli exclusion principle. The best way to illustrate is to fill up a bus with single people. They will tend to fill the empty seats first and then start sitting two people to a seat. In the same way due to energy considerations, an orbital can only have a maximum of two spin paired electrons in it. Anymore is energetically unfavorable. The same is true with each energy level. Each one can only hold a certain maximum of electrons. 1 = 2 2 = 8 3 =18 4 = 32 So with iron which has 26 electrons, they need 4 energy levels to fit these electrons in.
32 electrons can fit
2 can fit in the first energy level, 8 can fit in the second, and there is an infinite number that can fit in the 3rd.

2
8 (2s2, 2p6)
I think the answer for the 2nd principle energy level is 8 electrons
2 electrons

On the first shell you can only fit 2. 2nd shell is 8. 3rd shell is 18.
Answer this question… The extra electrons begin to fill the next energy level.
