If the radius of the 3^rd Bohr’s orbit of hydrogen atom r₃ and the radius of 4^th Bohr’s orbit is r₄. Then:

alok kumar singh

Radius of Bohr’s orbit $R_{n} = 0.529 \overset{o}{A} \times \frac{n^{2}}{z}$

Radius of Bohr’s orbit for hydrogen, $R_{n} = 0.529 \overset{o}{A} \times n^{2}$

For third orbit (R₃) = $0.529 \overset{o}{A} \times 9$ = r₃ and

Fourth orbit (R₄) = $0.59 \overset{o}{A} \times 16 = r_{4}$

$∴ r_{4} = \frac{16 r_{3}}{9}$

For irreversible expansion of an ideal gas under isothermal condition
ΔU = 0, ΔS (Total) ≠ 0

If radius of second Bohr orbit of the He?ion is 105.8pm, what is the radius of third Bohr orbit of Li²⁺ ion?

Vishal Baghel

105.8 × (2/4) = 52.9 pm ⇒ r_Li+ + r_X- = 52.9 × (3²/3) = 158.7 pm

Given below are two statements:
Statement I: Bohr's theory accounts for the stability and line spectrum of Li²? ion.
Statement II: Bohr's theory was unable to explain the splitting of spectral lines in the presence of a magnetic field.
In the light of the above statements, choose the most appropriate answer from the options given below:

Raj Pandey

Bohr's theory accounts for the line spectrum of single electron species but Li? has two electrons. Bohr's theory fails to explain splitting of spectral lines in presence of magnetic field i.e. Zeeman effect.

The difference between the radii of 3rd and 4th orbits of Li²⁺ in ΔR₁.. The difference between the radii of 3rd and 4th orbits of He⁺ is ΔR₂. Ratio ΔR₁: ΔR₂ is:

alok kumar singh

ΔR? = (a? /3) (16 – 9)
ΔR? = (a? /2) (16 – 9)
∴ ΔR? /ΔR? = 2/3
