They have very high ionization energy. If an element forms an anion (which means it's a non-metal), that means it gains electrons. Ionization energy means to lose electrons, so this "goes against the grain" of what they want to do. Ionization energy typically applies to metals, because metals lose electrons.

Which energy is the energy that can be taken to remove an electron form its shell?

This energy is called ionization energy and is different for each chemical element.


Why Xenon can form compounds with fluorine?

The size of xenon allows the inner electrons to shield the valence shell electrons reducing the ionization energy. The ionization energy is only low enough to allow reactions with the most electronegative elements.


What does a nonmetal elements need to do to form an anion?

A non metal must gain one or two electrons to form an anion


Out of sodium potassium rubidium and cesium Which element has the greatest ionization energy?

Sodium has the greatest ionization energy of the four elements listed from column 1 of a wide form periodic table. Among this group of metals that readily form cations, the largest always has the lowest ionization energy and the smallest has the most. This is generally ascribed to the fact that the valence shell electron is further from the nucleus in the largest element and nearest in the smallest element.

Is alkaline-earth element anion?

Alkaline-earth elements form cations.


What it ionization energy?

This is the energy needed to extract an electron from an atom in gaseous phase, to form a cation.


Is an Atoms with higher ionization energy usually form cations?

No that is incorrect. Normally atoms with a low ionization energy form cations since they are able to easily lose an electron therefore making it a cation. On the other hand something with a high ionization energy would generally have a high electro-negativity therefore tending to gain electrons to form anions.
