The radii of second orbit of he+ is
WebbFor the second Bohr orbit, n = 2. Atomic number of Li 2 + is z = 3. ∴ r n = n 2 × a 0 z ⇒ r n = 2 2 × a 0 3 r n = 4 a 0 3. Therefore, the radius of second Bohr orbit, in terms of the Bohr radius, 𝑎 0 , in Li 2 + is option (C) 4 a 0 3. Suggest Corrections. 1. Webb20 juli 2024 · BarrettArcher Answer : The energy and radius of second orbit of ion are, -13.6 ev and 105.8 pm respectively. Solution : Formula used for energy of orbit of ion or hydrogen like atom will be, Formula used for the radius of the orbit will be, (in pm) where, = energy of orbit = radius of orbit n = number of orbit Z = atomic number
