Web9 de fev. de 2016 · Note the wikipedia atomic orbitals article which says an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. Later on, the article says the electrons do not orbit the nucleus in the sense of a planet orbiting the sun, but instead exist as standing waves.

WebElectricity is the movement of electrons between atoms. Electrons usually remain a constant distance from the atom's nucleus in precise shells. The shell closest to the nucleus can hold two electrons. The next shell can hold up to eight. The outer shells can hold even more. Some atoms with many protons can have as many as seven shells with ...
