Question

consider the bohr model of an atom.

part 1 of 2

complete the following sentence.

in the bohr model, light is select when an electron moves from a higher-energy orbital to a lower-energy orbital.
options: absorbed, emitted

part 2 of 2

classify whether each transition will absorb or release light (or energy).

transition | classification
from n=7 to n=2 | select
from n=1 to n=2 | select
from n=4 to n=3 | select

Explanation:

Part 1 of 2

In the Bohr model, when an electron moves from a higher - energy orbital to a lower - energy orbital, energy is released in the form of light. So light is emitted.

When an electron moves from a higher principal quantum number (\(n = 7\)) to a lower principal quantum number (\(n = 2\)), it is moving from a higher - energy orbital to a lower - energy orbital. So energy (light) is released.

When an electron moves from a lower principal quantum number (\(n = 1\)) to a higher principal quantum number (\(n=2\)), it is moving from a lower - energy orbital to a higher - energy orbital. So energy (light) is absorbed.

Answer:

emitted

For the transition from \(n = 7\) to \(n=2\):
