MCQ
Find the true statement.
  • A
    An electron will not lose energy when jumping from the $1^{\text {st }}$ orbit to the $3^{\text {rd }}$ orbit.
  • B
    An electron will not give energy when jumping from the $1^{\text {st }}$ orbit to the $3^{\text {rd }}$ orbit.
  • C
    An electron will release energy when jumping from the $1^{\text {st }}$ orbit to the $3^{\text {rd }}$orbit.
  • An electron will absorb energy when jumping from the $1^{\text {st }}$ orbit to the $3^{\text {rd }}$ orbit.

Answer

Correct option: D.
An electron will absorb energy when jumping from the $1^{\text {st }}$ orbit to the $3^{\text {rd }}$ orbit.
An electron will absorb energy when jumping from the $1^{\text {st }}$ orbit to the $3^{\text {rd }}$ orbit.
Only by absorbing energy, an electron will be able to jump from the first orbit to the third orbit in the atomic spectrum.
