WebApr 8, 2024 · The ratio of the difference in the radius between ${4^{th}}$ and ${3^{rd}}$ orbit of H-atom and that of $\Rightarrow L{i^{2 + }}$ ion is $3:1$. So, the correct answer is Option B. Note: We know that the Bohr radius is a constant that is similar to the distance between the nucleus and the electron in an atom of hydrogen in its ground state. WebJul 5, 2024 · we have to find ratio of radius of first three orbits of Lithium ion, Li²+. from Bohr's theory, radius of nth orbit is given by, A° where n is orbit number and Z is atomic number. so, radius of first orbit , n = 1 =0.529 × 1²/ (3) = 0.529/3 A° radius of 2nd orbit, n = 2, = 0.529 × (2)²/3 = 0.529 × 4/3 A° radius of 3rd orbit , n = 3

Web(ii) Radius of Bohr’s nth orbit for hydrogen atom is given by, rn = (0.0529 nm) n2 For, n = 5 r5 = (0.0529 nm) (5) 2 r5 = 1.3225 nm Popular Questions of Class 11 Chemistry Q:- Calculate the amount of carbon dioxide that could be produced when (i) 1 mole of carbon is burnt in air. (ii) 1 mole of carbon is burnt in 16 g of dioxygen. WebUsing the Bohr model, determine the energy in joules of the photon produced when an electron in a He+ ion moves from the orbit with n = 6 to the orbit with n = 3. (Assume that the Bohr constant and radius are 2.179 10e−18 J and 5.292 10e−11 m, respectively.) 7.263e-19 WebMar 17, 2024 · The Bohr Theory gives accurate values for the energy levels in hydrogen-like atoms, but it has been improved upon in several respects. Hence, the radius of 2nd and 3rd Bohr orbit in a hydrogen atom is 2.116 and 4.761 Angstrom. Note: There are certain limitations to Bohr’s theory. cooling inverter
