WebEvery subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second … Web18 de mar. de 2015 · Mar 18, 2015. The electrons in an atom move around the nucleus in regions known as electron shells. Each electron shell can only contain a certain number of electrons. Electrons are placed in the lower energy level first and when this is completely filled, we move on to the second energy level and so on. The way the electrons are …
