WebRadius of the Bohr's orbit is given by,r= 4π 2mZe 2h 2n 2Substituting values of h, m for helium ion and the electronic charge r may be calculated asr= Z0.529n 2A 0Where 0.529A 0 is is the Bohr's radius a 0=0.529Substituting Z=2, n=2r=2a 0A 0. WebAnswer: Bohr’s distance of the center of the electron from the center of proton in hydrogen atom is 52.9 pm and its ionization energy is 13.60 eV. The first ionisation energy of helium atom is 24.59 eV. Hence the corresponding distance of each electron in helium atom is D=52.9X13.60/24.59= 29.3 p... crystal meth definition drug

WebFeb 20, 2024 · The first is the Bohr radius, or the smallest orbital radius \(a\), given for \(n=1\), \[\begin{align*} ... It cannot be applied to multielectron atoms, even one as simple as a two-electron helium atom. Bohr’s model is a semiclassical model. The orbits are quantized (quantum mechanical) but are assumed to be simple circular paths (classical ... WebOct 2, 2024 · Whenever an electron shell is filled, adding another electron will cause a step-change in the atomic radius as can be seen in the jagged graph in one of the answers above. Helium turns out to be the smallest atom on that graph, which is one of the reasons it was discovered in the sun before it was discovered on earth. Share.
