Question

For a hydrogen- like atom, classify these electron transitions by whether they result in the absorption or emission of light:

n=3 to n=5,
n=1 to n=3,
n=3 to n=2,
n=2 to n=1
Ignoring the sign, which transition was associated with the greatest energy change?

Answer 1

From higher state to lower state the transitions will be emission
AND,
From lower state to higher state the transitions will be absorption.
