Considering this, what is the number of electrons in the outermost energy level of an oxygen atom?In fact, the number of valence electrons goes up by one for each step across a period until the last element is reached. Neon, with its configuration ending in (2s^2 2p^6 ), has eight valence electrons. 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(n 2) electrons.

Subsequently, question is, how do you find the number of electrons in each energy level? 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.
Subsequently, one may also ask, how many electrons are in the neon outer shell?
So for the element of NEON, you already know that the atomic number tells you the number of electrons. That means there are 10 electrons in a neon atom. Looking at the picture, you can see there are two electrons in shell one and eight in shell two. Because shell two has eight electrons it is now full.
What is the Bohr diagram for neon?
Number Of Protons For Neon
Two electron shells surrounding the nucleus, containing 2 electrons in the n=1 shell and 8 electrons in the n=2 shell. Bohr's model of the atom described the atom as a series of energy levels called principle quantum shells, at progressively greater distance from the nucleus.
