हाइड्रोजन परमाणु की सबसे भीतरी कक्षा की त्रिज्या\(r_0=5.3\times10^{-11}m\)
मान लीजिए \(r_2 \) , n=2 पर कक्षा की त्रिज्या है।
संकल्पना:
हाइड्रोजन परमाणु की सबसे बाहरी कक्षा की त्रिज्या इस प्रकार दी गई है
- \(r_{n}=n^2r_0\)
स्पष्टीकरण:
कक्षा n=2 में त्रिज्या इस प्रकार ज्ञात की जा सकती है,
\(r_{n}=n^2r_0\)
\(r_2=(2)^2r_0\)
\(r_2=4\times5.3\times10^{-11}\)
\(r_2=21.2\times10^{-11}m=2.12\times10^{-10}m\)
अतः, सही उत्तर विकल्प-2 \(r_2=2.12\times10^{-10}m\) है।
