Question

Calculate the radius of the second orbit of hydrogen atom(h = 6.62×10-27 erg s, m = 9.1 × 10-28 g, e = 4.8 × 10-10 esu)
​

Answer 1

Explanation:

r= πmZe2n2h2εo

for hydrogen Z=1

∴ r=πme2n2h2εo

⇒3.14×9.1×10−31×(1.6×10−19)222×(6.63×10−34)2×(8.85×10−12)

=73.15×10−691556.07×10−80=21.3×10−11m
