In any bohr orbit of the hydrogen atom
WebOne of the fundamental laws of physics is that matter is most stable with the lowest possible energy. Thus, the electron in a hydrogen atom usually moves in the n = 1 orbit, the orbit in which it has the lowest energy. When the electron is in this lowest energy orbit, the atom is said to be in its ground electronic state (or WebThe Bohr model assumes that the Hydrogen atom electron moves in cirular orbits about the proton, but that only orbits of particular radii, r n are allowed where, r 1 is the radius of the smallest allowed orbit and n can take on integer values …

WebBohr considered circular orbits. Classically, these orbits must decay to smaller circles when photons are emitted. The level spacing between circular orbits can be calculated with the … WebAug 28, 2024 · Bohr sought to avoid an atomic catastrophe by proposing that certain orbits of the electron around the nucleus could be exempted from classical electrodynamics and remain stable. The Bohr model was quantitatively successful for the hydrogen atom, as we shall now show.
http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch6/bohr.html WebThe Bohr model only worked for Hydrogen atoms, and even for hydrogen it left a lot unexplained. The reason it works somewhat for hydrogen is that even though the electrons are not in orbits there are certain energy concepts for orbits that have more universal applicability. 2 comments ( 3 votes) April Tucay 8 years ago
WebUsing Planck's constant, Bohr obtained an accurate formula for the energy levels of the hydrogen atom (see Figure 3). He postulated that the angular momentum of the electron is quantized--i.e., it can have only discrete values. He assumed that otherwise electrons obey the laws of classical mechanics by traveling around the nucleus in circular ... WebApr 13, 2024 · A hydrogen-like atom consists of a tiny positively-charged nucleus and an electron revolving around the nucleus in a stable circular orbit. Bohr's Radius: If 'e,' 'm,' and 'v' be the charge, mass, and velocity of the electron respectively, 'r' be the radius of the orbit, and Z be the atomic number, the equation for the radii of the permitted ...
WebApr 15, 2024 · If 'e,' 'm,' and 'v' be the charge, mass, and velocity of the electron respectively, 'r' be the radius of the orbit, and Z be the atomic number, the equation for the radii of the permitted orbits is given by r = n 2 xr 1, where 'n' is the principal quantum number, and r 1 is the least allowed radius for a hydrogen atom, known as Bohr's radius ...
