Period. It doesn’t matter if you’re sitting in a college classroom or a coffee shop. We don’t learn anything we don’t want to learn. Those people who take the time and initiative to pursue knowledge on their own are the only ones who earn a real education in this world. Take a look at any widely acclaimed scholar, entrepreneur or historical figure you can think of. If you’re interested in learning something new, this article is for you. Atomic orbital. The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz.

Atomic orbital

The colors show the wave function phase. These are graphs of ψ(x, y, z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x, y, z)2 functions that show probability density more directly, see the graphs of d-orbitals below. Each orbital in an atom is characterized by a unique set of values of the three quantum numbers n, ℓ, and m, which correspond to the electron's energy, angular momentum, and an angular momentum vector component, respectively. Any orbital can be occupied by a maximum of two electrons, each with its own spin quantum number. Atomic orbitals are the basic building blocks of the atomic orbital model (alternatively known as the electron cloud or wave mechanics model), a modern framework for visualizing the submicroscopic behavior of electrons in matter.

Matter is anything that has mass and takes up space (volume). All matter is made up of atoms. The atom has a nucleus, which contains particles of positive charge (protons) and particles of neutral charge (neutrons). Surrounding the nucleus of an atom are shells of electrons - small negatively charged particles. Open Yale courses.
