How are atoms built
Electrons are not always confined to their specific shells. If an atom absorbs a photon of light with enough energy — say an ultraviolet photon from a hot star— this absorbed energy can cause an electron to transition to a higher energy level for a short time. This is an unstable situation, however, so the electron … Ver mais It has been known that elements are broken down into basic units of a given weight since the early 1800s, in an insight that came from the … Ver mais Not all atoms are stable.

WebIn a Van de Graaff generator, invented in 1929 by Robert J. Van de Graaff, an endless rubber or fabric belt carries electric charges from a roller at the base of the device and deposits them inside a hollow metal electrode at the top. This causes a high voltage to develop between electrodes at the top and bottom of the apparatus. [20] WebMolecules are made when two or more atoms chemically bond together.
