Question

1. take a look at the bohr model. an electron fell from the second energy level to the first energy level. the energy was released as light.

a. label which energy level (ring) is the excited state of the electron and which is the ground state of the electron on the model.
b. when the electron transitions from the excited to the ground state it _________ energy.

Explanation:

Part (a)

In the Bohr Model, the excited state of an electron is when it is in a higher energy level (has absorbed energy to move to a higher orbit), and the ground state is the lowest energy level (the most stable, lowest orbit). Here, the electron fell from the second energy level to the first. So the second energy level (higher - energy orbit) is the excited state, and the first energy level (lower - energy orbit) is the ground state. On the model, label the higher - energy orbit (second energy level) as the excited state and the lower - energy orbit (first energy level) as the ground state.

When an electron transitions from an excited state (higher energy level) to the ground state (lower energy level), according to the Bohr Model and the principles of atomic energy levels, the electron releases energy (in the form of light, as given in the problem).

Answer:

Excited state: Higher - energy orbit (second energy level); Ground state: Lower - energy orbit (first energy level)
