What energy is needed to remove an electron from its outer most shell?

This is called the ionization energy and an is different for each electron in the atom. Electrons in the outer shell (furthest from the nucleus) have the lowest ionization energy, electrons in the innermost shell (closest to the nucleus) have the highest ionization energy.

∙ 11y agoIt depends on the element. If it is pretty unstable, it is easy to take away. If the element is really stable, like if it's a noble gas, it takes way more energy. It can also depend on the energy level. The bigger the energy level, the more energy it takes to take it away. For example, you don't need much energy to take away an electron from energy level 1, but it's REALLY hard to take an electron away from level 6.

Why is the ionization energy needed to remove the first two electrons from Magnesium atoms relatively low?
magnesium has a 2 valence electrons. because the third electron is not a valence electron, or in the outer shell, much more energy would be needed to remove it
Why is it difficult to remove electron from halogens?
In their outer electron shell, halogens have 7 valence electrons, one less than the number needed for a full shell. Therefore, it is much, much easier for the halogen to gain an electron in bonding than for it to lose 7 - the ionization energy (energy required to remove an electron from an atom) is quite high.

What is ionization energy?
Briefly, it is the energy required to completely remove a valence (outer shell) electron from its atom when forming an ionic bond.See related links below for more info
How does the size of the atom affect the energy needed to remove an electron?
As the size of an atom increases, the energy needed to remove an electron decreases. As the size of an atom increases, the atomic radius increases: the distance between the nucleus and the outer electron shell becomes greater. This means that the positive nuclear charge has less of an effect on the negatively charged electron, so the attractive force between the nucleus and the electron is weaker. Less energy is required to overcome the weaker force.

Yes
How many electrons are needed in the outer energy level to make H stable?
Only 1 electron needed to make H stable.

What does ionization energy remove from an atom of an element?
Ionization energy and electron affinity for cations and anions, respectively.

The Valence electron
Can an electron in the outer energy level be called a valence electron?
Yes, it is correct.
