The bond length (d) of a diatomic molecule is given by the equation: d = \( n^2 / Z \) * a0, where n is the principal quantum number, Z is the atomic number, and a0 is the Bohr radius. If the atomic number is 8, the principal quantum number is 3, and the Bohr radius is 5.29 x 10^\( -11 \) m, calculate the bond length (d).

A. 1.0 x 10^\( -10 \) m

B. 2.0 x 10^\( -10 \) m

Correct Answer C. 3.0 x 10^\( -10 \) m

D. 4.0 x 10^\( -10 \) m

Correct Answer

Correct Option:

3.0 x 10^\( -10 \) m
