Question

For a hydrogen‑like atom, classify the electron transitions according to whether they result in the absorption or emission of light. Absorption Emission Answer Bank Ignoring sign, which transition is associated with the greatest energy change? n=3 to n=5

Answer 1

The complete question is

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

n=3 to n=2

n=3 to n=5

n=1 to n=3

n=2 to n=1

Ignoring sign, which transition is associated with the greatest energy change

Answer:

Absorption n=1 to n = 5, n = 3 to n = 5

Emission n= 3 to n= 2, n = 2 to n= 1

When you will calculate the energy difference from these transition using the formula

E =
`-13.6 *(z)/(n^2)`

Delta E(n=3 to n= 2) = 13.6* 5/36 = 1.888eV

Delta E (n=3 to n= 5) = 0.967eV

Delta E ( n= 1 to n= 3) = 12.088eV

Delta E ( n= 2 to n=1) = 10.2eV

clearly n=1 to n = 3 has the greatest energy.
