In the animation, you can see that the electrons occupy different orbitals according to the energy level of each orbital. A single box represents an orbital. The unpaired electron is represented as 1 whereas the paired electrons in the same orbital are represented by two arrows pointing in opposite directions: 1. Watch the animation and identify which of the following statements are correct. Check all that apply. View Available Hint(s) The He atom has two electrons that have parallel spin in its 1s orbital. The C atom has two unpaired electrons. Electrons generally occupy the lowest energy orbital first. In the Li atom, the 3s, 3p, and 3d orbitals have different energies. The arrangement of the orbitals is the same in a multielectron atom and a single-electron atom. The He atom has one electron each in 1s and 2s orbitals.
