A) \[0.27\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[1.27\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[2.12\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[3.12\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: C
Solution :
Radius of the \[{{n}^{th}}\]orbit for hydrogen atoms\[{{r}^{n}}=0.529\times {{n}^{2}}\] Radius of the \[(n=2)\] orbit for hydrogen atom\[{{r}_{2}}=0.529\times {{(2)}^{2}}\] \[=2.116\overset{\text{o}}{\mathop{\text{A}}}\,=2.12\overset{\text{o}}{\mathop{\text{A}}}\,\]
