WebFeb 20, 2014 · There's an important distinction between "the number of electrons possible in a shell" and "the number of valence electrons possible for a period of elements". There's space for $18 \text{e}^-$ in the 3rd shell: $3s + 3p + 3d = 2 + 6 + 10 = 18$, however, elements in the 3rd period only have up to 8 valence electrons. Web-the index means how many electrons the orbital contains. Therefore, 1s^2 means that there is orbital s with 2 electrons in shell 1 . ... if you looked at the atom from the outside you would see a fuzzy cloud. Of course atoms have many electrons so you have various electrons in different energy quanta states orbiting around the nucleus.
