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.
1. In this transition an electron moves from the n = level to the n = level.
2. Energy is_______ in this process.
A. Absorbed
B. Emitted
3. The electron moves ___________ the nucleus.
A. Closer to
B. Further from

Answer:

1. ELECTRON MOVES FROM THE n = 4 to n = 1 LEVEL

2. ENERGY IS EMITTED

3. THE ELECTRON MOVES CLOSER TO THE NUCLEUS

Explanation:

the question is incomplete as the picture is not shown but here is the picture and the solution.

Bohr model of the hydrogen atom shows that electrons would not emit energy but emit or absorb protons as it moves to a lower or higher energy levels respectively. In this question as shown in the picture below, the hydrogen atom moves from energy level 4 to energy level 1 and in such transition, energy is emitted and returns to its ground state after been excited to a higher level o n equals to 4. The energy emitted follows the law of conservation of energy. That is the amount of energy needed to excite the atom to a higher level is emitted upon transition back to the ground state.

The size of the hydrogen atom will also reduce and the electron will move closer to the nucleus. This is because as energy increases, the electron is found at a greater distance away from the nucleus and vice versa. And as the electron moves farther away the electrostatic force between it and the nucleus reduces and it is loosely held by the nucleus and vice versa, As the case of the question, the electron moves closer to the nucleus and it is strongly attached to the nucleus due to increase electrostatic attraction between it and the nucleus.

Answer:

In this transition, energy is emitted

The electron moves closer to the nucleus

Explanation:

In the Bohr's model of the atom, electrons occupy specific energy levels shown by the principal quantum number. An electron that is stationary in its orbit does not radiate energy.

However, an electron may absorb energy and be excited to higher energy levels or emit energy when descending from a higher to a lower energy level. This energy is usually observed as a photon of light of appropriate wavelength and frequency.

In the image, the electron descends from energy level n=4 to energy level n=1. Since it has moved from a higher to a lower energy level, energy is emitted. Recall that energy levels increase outwards from the nucleus. Since n=1 is closest to the nucleus, the electron has moved closer to the nucleus. Hence the answers above.
