Tardigrade Admin · Accepted Answer

Energy of nth orbit of hydrogen atom En=-(13.6/n2) eV The energy absorbed, when an electron jumps from the first energy level (n=1) to second level (n=2) =-13.6 ×((1/n12)-(1/n22)) =-13.6[(1/(1)2)-(1/(2)2)] =-13.6 × (3/4) =-10.2 eV

Q. What will be the amount of energy absorbed when an electron jumps from first orbit to second orbits? (If the value of energy in nth orbit of H-atom is expressed as En​=−n213.6​eV)

- 3.4 eV

- 6.6 eV

-8.1 eV

-10.2 eV

Energy of nth orbit of hydrogen atom En​=−n213.6​eV The energy absorbed, when an electron jumps from the first energy level (n=1) to second level (n=2) =−13.6×(n12​1​−n22​1​) =−13.6[(1)21​−(2)21​] =−13.6×43​ =−10.2eV

Q. What will be the amount of energy absorbed when an electron jumps from first orbit to second orbits? (If the value of energy in $n$ th orbit of $H$ -atom is expressed as $E_{n} = - \frac{13.6}{n ^{2}} e V)$
