Why do electron-electron-interactions raise the energy level?

In summary, the energy levels of orbiting electrons can be raised when an electron is fired at an orbiting electron that is at its ground state. This is because the incoming electron can transfer energy to the orbiting electron, causing it to speed up and increase its energy level.

Hi,

This is probably a really simple question, I am just trying to get my head around why electron-electron-interactions raise the energy level. If electrons repulse each other, why does this cause the energy levels to increase?

Thanks

I'll assume you know that energy is conserved, and that by "raise the energy level" you mean energy is transferred from one electron to the other, which raises that other's energy level. For example, an electron is fired into an atom and it might raise the energy of one of the orbiting electrons.

When an incident electron strikes an orbiting electron, depending on the angle, phase, and position it strikes, it might speed up the orbiting electron, slow it down, or do neither. However, if the orbiting electron is already at its ground state, then it can't be slowed down any further. So one can make the statement, "If an electron is fired at an orbiting electron that is at its ground state, then the energy level of the orbiting electron will either stay the same or be raised"
 

1. What are electron-electron interactions?

Electron-electron interactions refer to the interactions between two or more electrons in an atom or molecule. These interactions play a critical role in determining the energy levels and properties of electrons.

2. Why do electron-electron interactions raise the energy level of electrons?

Electron-electron interactions involve the repulsion between negatively charged electrons. When two or more electrons come close to each other, they repel each other, causing the energy level of the electrons to increase.

3. How do electron-electron interactions affect the behavior of electrons?

Electron-electron interactions affect the behavior of electrons by influencing their movement and distribution within an atom. These interactions can cause electrons to occupy different energy levels and affect their ability to move freely.

4. Can electron-electron interactions lower the energy level of electrons?

Yes, electron-electron interactions can cause the energy level of electrons to decrease. This can occur when electrons are attracted to positively charged particles, such as protons in the nucleus, which can pull the electrons closer and lower their energy levels.

5. How do electron-electron interactions contribute to the stability of atoms and molecules?

Electron-electron interactions play a crucial role in maintaining the stability of atoms and molecules. These interactions help to balance the repulsion between negatively charged electrons and the attraction between electrons and positively charged particles, allowing atoms and molecules to maintain their overall structure and stability.
