Radius of first bohr orbit of hydrogen in cm
WebThe 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 on. The Coulomb potential (5) generalizes to V(r) = ¡ Ze2 r; (18) the radius of the orbit (13) becomes r n = n2a 0 Z (19) and the energy ... WebSolution The correct option is D 9x ∘A Bohr's radius for nth orbit, rn = 0.529[ n2 Z] ∘A where, n=Energy level, Z =Atomic number For H atom: n=1, Z =1 rH =0.529[12 1] ∘A = 0.529 ∘A = x ∘A So, for third Bohr's orbit n = 3 ∴ rn = x×(32) = 9x ∘A Suggest Corrections 2 Similar questions 2
