Question

If an electron is revolving in its Bohr orbit having Bohr radius of 0.529 mathringA , then the radius of third orbit is (A) 4.761 mathringA  (B) 5125 nm (C) 4234 nm (D) 4496 mathringA

Tardigrade Admin · Accepted Answer

r n =0.529 × ( n 2/ z ) n =3 =0.529 × 9=4.761 mathringA

Q. If an electron is revolving in its Bohr orbit having Bohr radius of $0.529 \overset{˚}{A}$ , then the radius of third orbit is

$4.761 \overset{˚}{A}$

$5125 nm$

$4234 nm$

$4496 \overset{˚}{A}$

$r_{n} = 0.529 \times \frac{n ^{2}}{z} n = 3$
$= 0.529 \times 9 = 4.761 \overset{˚}{A}$

Q. If an electron is revolving in its Bohr orbit having Bohr radius of 0.529A˚, then the radius of third orbit is

4.761A˚

5125nm

4234nm

4496A˚
