How many electrons are in each ring of an atom?
The easiest way to find the number of protons, neutrons, and electrons for an element is to look at the element’s atomic number on the periodic table. That number is equal to the number of protons. The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element.
Each orbital can hold two electrons. One spin-up and one spin-down. This means that the 1s, 2s, 3s, 4s, etc., can each hold two electrons because they each have only one orbital. The 2p, 3p, 4p, etc., can each hold six electrons because they each have three orbitals, that can hold two electrons each (3*2=6).
In brief, the rings have 2, 8, 18 and 32 (and 50, conceptually) electrons. The reasons why this is the case are not really explained in the Bohr model but are easily explained using the more-complex quantum explanation involving orbitals.
two electrons
Each successive shell can only hold a certain number of electrons. The innermost shell is filled first. This shell can contain a maximum of two electrons. The second shell can hold a maximum of eight electrons….Electron shells.

Number of Electrons in Atoms of the First Twenty Elements in the Periodic Table
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
