WebFeb 8, 2015 · 1 Answer. Sorted by: 3. I assume you refer to Bohr's atomic model. The energy of an electron in Bohr’s orbit of Hydrogen atom is given by the expression: E n = 2 π 2 m e 4 Z 2 n 2 h 2 ( 4 π ϵ 0) 2 = − 13.6 Z 2 n 2 e V. Since Z = 1 for hydrogen, the above equation can be further simplified. Now just plug in the required values. WebThe slight discrepency with the experimental value for hydrogen (109,677) is due to the ﬂnite proton mass. This will be corrected later. The Bohr model can be readily extended to hydrogenlike ions, systems in which a single electron orbits a nucleus of arbitrary atomic number Z. Thus Z = 1 for hydrogen, Z = 2 for He+, Z = 3 for Li++, and so ... j balvin black face

WebMar 24, 2024 · Balmer's formula had been discovered earlier, but Bohr was unaware of that. Bohr said later: "As soon as I saw Balmer's formula, the whole thing was immediately clear to me." Bohr realized that the existence of a series in the spectrum shows that for Hydrogen, with its single electron there isn't just a single stable ground state, there is a ... WebYes. This formula will work for hydrogen and other unielecton ions like He+, Li^2+, etc. When there are more than one electrons, then there is repulsion between those electrons due to their same negative charge. The formula then breaks down. Also note, the Bohr model is not what actually happens. WebImportant equations of Bohr’s model. The radius of Bohr’s stationary orbit $r_n = n^2 ( \frac {h^2 \epsilon_0}{\pi m Z e^2}) $ Where, n is an integer, r n is the radius of the n-th orbit, H is the Planck’s constant, is the electric … low women\u0027s boots
