where electrons are found

All the possible that are subshells where electrons could possibly be found

This means that in the first shell only two electrons are possible and they would be found in the 1s (2 electrons) subshell. In the second shell, 8 electrons are possible and would be found in the 2s (2 electrons) and the 2p (6 electrons) subshells. Each subshell is further divided into orbitals.

5.12: Energy Level

Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Electrons are tiny, negatively charged particles in an atom that move around the positive nucleus at the center. Energy levels are a little like the steps of a staircase.

The tiny superscripts say how many electrons live in each orbital, the letters represent the orbitals that are available, and the big numbers say which energy level the orbitals are found in. Remember that the total number of electrons just equals the total number of protons, and so the superscripts add up to 8, the atomic number of oxygen.

Electrons are found within the lobes. The plane (or planes) that the orbitals do not fill are called nodes. These are regions in which there is a 0 probability density of finding electrons. For example, in the d yx orbital, there are nodes on planes xz and yz. This can be seen in Figure (PageIndex{1}).
