### Decreasing gap between energy level

Why does the gap between different shells decrease as the level goes up?

### Re: Decreasing gap between energy level

The energy that the electrons needed to emit and absorb to jump to another level was lower, so the gap became smaller. For example, the energy that is needed to be absorbed to get from n=1 to n=2 is more than the energy that needs to be absorbed when going from n=2 to n=3. Therefore, the gap between n=2 and n=3 is smaller.

### Re: Decreasing gap between energy level

The gaps between the energy levels decrease as the levels increase because as the levels increase, they get farther from the "gravity" of the nucleus, which means that higher energy levels require less energy to remove the electrons from said level. Vice versa, lower energy levels require more energy to remove electrons because they are closer to the nucleus.

As the electrons get farther from the nucleus, the pull of the nucleus becomes weaker. Therefore, it takes less energy to remove that electron from that level.

Electrons closer to the nucleus are more affected by the pull and thus require more energy to remove. The further the electrons are from the nucleus, the weaker the pull, which results in less energy required to remove electrons.

### Re: Decreasing gap between energy level

The pull of the nucleus decreases at higher energy levels because of the distance and because of the shielding provided by the electrons in lower energy levels.

### Re: Decreasing gap between energy level

As an electron gets farther away from the nucleus, the "pull" of the nucleus decreases in strength. Therefore the easier it is for an electron to jump to a higher energy level the farther away from the nucleus it is.
