Question

Bohr's theory is applicable to which of the following set of species?

• A. $H^{+},H{e}^{2+},L{i}^{3+},B{e}^{4+}$
• B. $H,H{e}^{+},L{i}^{2+},B{e}^{3+}$
• C. $H^{+},L{i}^{+},H{e}^{+},B{e}^{+}$
• D. For all these sets

Answer 1

The correct option is B $H,H{e}^{+},L{i}^{2+},B{e}^{3+}$

Bohr's model is only applicable to uni-electronic species.
