If the lobe lies along the x plane, then it is labeled with an x, as in 2px. Since electrons all have the same charge, they stay as far away as possible because of repulsion. According to Hund's principle, the first electron will enter in the clockwise direction and the next electron will enter the 1s orbital in the anti-clockwise direction. An element's electronic configuration is a symbolic representation of how its atoms' electrons are distributed across different atomic orbitals. The electron configuration of a selenium atom can be done in two ways. The nucleus is the lobby where the protons and neutrons are, and in the floors above, we find the rooms (orbitals) with the electrons. To the level of an orbital, this comes down to one of the two electrons that share an orbital having spin-up, which is given by the spin quantum number #m_s = +1/2#, and the other having spin-down, which is given by #m_s = -1/2#.
