Question

which statement is true about the electrons in the bohr model of an atom?

• they exist at specific energy levels.
• they are equally close to the nucleus.
• they cannot move from one orbital to another.
• they give off energy as they jump to a higher level.

Explanation:

• For the option "They exist at specific energy levels": According to the Bohr model, electrons orbit the nucleus in specific, quantized energy levels (orbits).
• For "They are equally close to the nucleus": Electrons in different energy levels are at different distances from the nucleus (closer levels have lower energy, farther have higher), so this is false.
• For "They cannot move from one orbital to another": Electrons can move between energy levels by absorbing or emitting energy, so this is false.
• For "They give off energy as they jump to a higher level": Electrons absorb energy to jump to a higher energy level and emit energy when falling to a lower level, so this is false.

Answer:

They exist at specific energy levels.
