Diameter of electron
WebSep 11, 2024 · The Lamb shift, named for the American physicist Willis Lamb, who first attempted to measure it in 1947, reveals the proton’s radius in the following way: When an electron orbits the proton in the 2S state, … WebF = B e v where B is the magnetic field strength, e is the charge on the electron and v their speed; Given that the electrons are going in a circle, we know that this force must have a size of; mv 2 / r where m is the mass of the electron and r is the radius of the orbit. So you can say that: B e v = mv 2 / r; so B e = mv / r (equation 2)

The Bohr radius (a0) is a physical constant, approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.29177210903(80)×10 m. WebAug 12, 2024 · Predicting Relative Sizes. Because electrons are what take up space in atoms, the result is that the size of the biggest filled orbital determines the size of the atom or ion. Sizes of orbitals depend on the quantum numbers (n = 1, n = 3, etc.) and also on the effective nuclear charge. An orbital of any type will get smaller as the effective ...
