Question

the radius of innermost electron orbit of a hydrogen atom is 5.3 × 10 to the power minus 11 m.what is the radius of orbit in the second excited state??​

Answer 1

Ⓗⓞⓛⓐ

the radius of nth orbit of hydrogen atom is given by ,

rn = r ' n^2 ,

where,r ' = 5.3 × 10^-11 m

for second excited state ,

n = 3

r3 = 5.3 × 10 ^-11 × 9

= 4.77 × 10 ^ -10 m

Answer 2

Explanation:

the radius of nth orbit of hydrogen atom is given by ,

rn = r ' n^2 ,

where,r ' = 5.3 × 10^-11 m

for second excited state ,

n = 3

r3 = 5.3 × 10 ^-11 × 9

= 4.77 × 10 ^ -10 m.
