Electron

In summary, ionisation is the process of adding or removing electrons from an atom or molecule, resulting in the formation of ions. This can occur through various methods such as chemical reactions, exposure to high-energy radiation, or collisions with other particles. An electron can be ionised multiple times, and after ionisation, it can continue to move freely or be captured by another atom or molecule. Ionisation can significantly change the properties of an atom or molecule, making it more reactive, increasing its ability to conduct electricity, or changing its physical properties such as melting and boiling points. These changes are a result of the formation of ions and their interactions with other particles.

I understand that when an electron is excited it goes to a higher energy level and then relaxes to ground state releasing a photon; however, after ionisation of an electron takes place, where does the electron go if it is "removed" from the atom.

It just floats around freely, just like the parent ion.

1. Where does the electron go during ionisation?

During ionisation, the electron is removed from an atom or molecule and becomes a free electron, meaning it is no longer bound to the nucleus of the atom.

2. What is the process of ionisation?

Ionisation is the process of adding or removing electrons from an atom or molecule, resulting in the formation of ions. This can occur through various methods such as chemical reactions, exposure to high-energy radiation, or collisions with other particles.

3. Can an electron be ionised multiple times?

Yes, an electron can be ionised multiple times, meaning it can lose more than one electron and form multiple ions. This is known as multiple ionisation and can occur in atoms with multiple electrons in their outermost energy level.

4. What happens to the electron after ionisation?

The electron will continue to move freely in its surroundings, but it can also be captured by another atom or molecule, forming a new chemical bond. Additionally, the electron can recombine with the ion it was removed from, releasing energy in the form of light.

5. How does ionisation affect the properties of an atom or molecule?

Ionisation can significantly change the properties of an atom or molecule. For example, ionisation can make an atom or molecule more reactive, increase its ability to conduct electricity, or change its melting and boiling points. These changes in properties are due to the formation of ions and their interactions with other particles.
