Energy and radius of first Bohr orbit of He⁺ and Li²⁺ are [Given RH = 2.18×10⁻¹⁸ J, a0 = 52.9 pm]
A
En(Li²⁺) = −19.62×10⁻¹⁸ J: rn(Li²⁺) = 17.6 pm; En(He⁺) = −8.72×10⁻¹⁸ J; rn(He⁺) = 26.4 pm
B
En(Li²⁺) = −8.72×10⁻¹⁸ J; rn(Li²⁺) = 26.4 pm; En(He⁺) = −19.62×10⁻¹⁸ J: rn(He⁺) = 17.6 pm
C
En(Li²⁺) = −19.62×10⁻¹⁶ J; rn(Li²⁺) = 17.6 pm; En(He⁺) = −8.72×10⁻¹⁶ J: rn(He⁺) = 26.4 pm
D
En(Li²⁺) = −8.72×10⁻¹⁶ J; rn(Li²⁺) = 17.6 pm; En(He²⁺) = −19.62×10⁻¹⁶ J: rn(He⁺) = 17.6 pm
