Question

1. in this transition an electron moves from the n = level to the n = level.
2. energy is

a. absorbed
b. emitted
in this process.

1. the electron moves

a. closer to
b. further from
the nucleus.
in the bohr model of the hydrogen atom, the electron occupies distinct energy states.
one transition between energy states of the hydrogen atom is represented by the picture on the left.

Explanation:

1. In the Bohr model, when an electron moves from a lower energy level ($n = 1$) to a higher energy level ($n=4$), it absorbs energy. This is because it needs to gain energy to overcome the electrostatic attraction of the nucleus and move to a more distant orbit.
2. As the electron moves from a lower energy level ($n = 1$) to a higher energy level ($n = 4$), it is moving to a state of higher potential energy. According to the Bohr model, energy is absorbed during such a transition.
3. The radius of the electron's orbit in the Bohr model is given by \(r_n=n^{2}r_1\) (where \(r_1\) is the radius of the first - orbit). As \(n\) increases from \(n = 1\) to \(n=4\), the value of \(n^{2}\) increases (\(1^{2}<4^{2}\)), so the electron moves further from the nucleus.

Answer:

1. \(n = 1\) to \(n = 4\)
2. A. Absorbed
3. B. Further from
