The image in my mind is of free electrons in an atom, careening in random ways.

The most widely studied set of quantum numbers is that for a single electron in an atom: not only because it is useful in chemistry, being the basic notion behind the periodic table, valence (chemistry) and a host of other properties, but also because it is a solvable and realistic problem, and, as such, finds widespread use in textbooks.

Erwin Schrödinger, meanwhile, developed a full - fledged «wave mechanics» to describe the behavior of electrons in atoms solely from the wave perspective.

The basic building blocks of the atomic nuclei are positively charged protons whose electric charge must be equal to the total charge of negative electrons in that atom.

When we shrink light's electromagnetic fields to nearly atomic length scales, then we've got to worry about how electrons in an atom responds to light.

Electron - flavor neutrinos are special because they can interact with the Earth: They alone can meaningfully interact with electrons in atoms.

Physicists from Ludwig - Maximilians - Universitaet (LMU) in Munich have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

We will be concerned, however, with mental models of systems which for various reasons can not be represented by replicas, such as the economy of a nation, the electrons in an atom or the biblical God.

Van der Waals interactions arise due to a temporary redistribution of electrons in the atoms and molecules.

That is the unimaginably short time scale on which processes such as the motion of an electron in an atom can be studied.

Researchers who want to predict the behavior of systems governed by quantum mechanics — an electron in an atom, say, or a photon of light traveling through space — typically turn to the Schrödinger equation.

«When positronium hits an atom, the electrons in the atom don't know what to do — do they stick with the nucleus, or try to chase after the positron?»

But when Danish physicist Niels Bohr showed that the electrons in atoms, too, must behave as quanta to account for observations, Einstein made a conceptual leap that troubled him even more.

On such a basis the Earth is a particle in the Solar System and the electron in an atom.

A technique called ab initio quantum chemistry (ab initio is Latin for «from the beginning») allows scientists to start from pure quantum mechanics — the theory that describes the behavior of subatomic particles — to calculate a molecule's properties based on the motions of the protons, neutrons and electrons in the atoms that compose it.

The results give researchers a potential new, solid - state tool for «attosecond science,» which explores processes like the motions of electrons in atoms and the natural vibrations of molecules.

In theory, this mathematical beast can be solved to give the probability that electrons in an atom or molecule will be in certain positions, giving rise to chemical and physical properties.
