There's nothing to lose! 12 Dozen Places To Educate Yourself Online For Free. Post written by: Marc Chernoff Email All education is self-education.
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. If you’re interested in learning something new, this article is for you. Note that some of the sources overlap between various subjects of education. Science and Health MIT OpenCourseWare – MIT OpenCourseWare is a free web-based publication of MIT course materials that reflects almost all the undergraduate and graduate subjects taught at MIT.Tufts OpenCourseWare – Tufts OpenCourseWare is part of a new educational movement initiated by MIT that provides free access to course content for everyone online. Business and Money History and World Culture Law Duke Law Center for the Public Domain – Duke University is counted amongst the best schools in the South.
Atomic orbital. The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz.
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. Electron properties Wave-like properties: Particle-like properties: Background: Atoms and Light Energy. Inside the Atom Just like bricks are the building blocks of a home, atoms are the building blocks of 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. Light Energy Each orbital has a specific energy associated with it.
The illustrations on this page are simplified versions of real atoms, of course. Identifying Individual Types of Atoms. Open Yale courses. Security Now! Episode Archive. OpenClassroom. Full courses.
