About the energy necessary to pull out the closest electron of a atom

In summary, the closest electron to an atom's nucleus is determined by its energy level and probability of being found near the nucleus. The energy necessary to pull out the closest electron is determined by the atom's ionization energy, distance from the nucleus, and strength of attractive force. This energy can be measured through experiments and is affected by the atom's properties such as its ionization energy, electron configuration, and atomic number. It also has a direct relationship to an element's chemical reactivity and bonding behavior.

Dear friends,
I was wondering what would be the necessary amount of energy to pull out the closest electron of an iron metal. I read that the energy required for the most distant electrons of the iron metal is about 9 thousand KJ/mol.

Thanks my sages@

For bulk iron?
That would be the work-function ... defining "closest" as the electrons with the least binding energy.

Exactly the same energies are involved in Auger effect.
 

1. What is the closest electron in an atom?

The closest electron to an atom's nucleus is the one that has the lowest energy level or the one with the highest probability of being found near the nucleus.

2. What is the energy necessary to pull out the closest electron?

The energy necessary to pull out the closest electron depends on the atom's ionization energy, which varies for different elements. It also depends on the distance of the electron from the nucleus and the strength of the attractive force between them.

3. How is the energy necessary to pull out the closest electron determined?

The energy necessary to pull out the closest electron can be determined by performing experiments in which a known amount of energy is applied to an atom, and the amount of energy needed to remove the closest electron is measured. This is known as the atom's ionization energy.

4. What factors affect the energy necessary to pull out the closest electron?

The energy necessary to pull out the closest electron is affected by the atom's ionization energy, the distance of the electron from the nucleus, and the strength of the attractive force between them. It is also affected by the electron's energy level and the number of other electrons in the atom.

5. What is the relationship between the energy necessary to pull out the closest electron and the atom's properties?

The energy necessary to pull out the closest electron is directly related to the atom's properties such as its ionization energy, electron configuration, and atomic number. It also plays a role in determining an element's chemical reactivity and bonding behavior.
