This number indicates how many orbitals there are and thus how many electrons can reside in each atom. Orbitals that have the same or identical energy levels are referred to as degenerate. An example is the 2p orbital: 2p x has the same energy level as 2p y. This concept becomes more important when dealing with molecular orbitals.
Dec 13, 2023 · An atomic orbital is characterized by three quantum numbers. The principal quantum number, n, can be any positive integer. The general region for value of energy of the orbital and the average distance of an electron from the nucleus are related to n. Orbitals having the same value of n are said to be in the same shell.
Apr 21, 2023 · For a given atom, the s orbitals also become higher in energy as n increases because of their increased distance from the nucleus. Orbitals are generally drawn as three-dimensional surfaces that enclose 90% of the electron density, as was shown for the hydrogen 1 s, 2 s, and 3 s orbitals in part (b) in Figure 1.2.2.
7.11: Atomic Orbitals. An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are ...

These are arbitrarily given the symbols px, py and pz. This is simply for convenience - what you might think of as the x, y or z direction changes constantly as the atom tumbles in space. The p orbitals at the second energy level are called 2p x, 2p y and 2p z. There are similar orbitals at subsequent levels - 3p x, 3p y, 3p z, 4p x, 4p y, 4p z ...
Electrons remain electrons, and as such their total spin angular momentum is 3√ 2 ℏ 3 2 ℏ, and the possible projection along any axis is quantized to +ℏ/2 + ℏ / 2 and −ℏ/2 − ℏ / 2. The total angular momentum in the electron cloud of an atom depends on the orbital and spin angular momenta of all the electrons.
