What is the word eletrovent

Explanation:

Electrovalent is a word often associated with chemical bonding in the field of chemistry. It is special type of bond that occurs between metals and non-metals.

These bond types are interatomic interactions occurring between two atoms to ensure that they attain stable configurations.

This bond type is also known as ionic bonds. It occurs between two species with a large electronegative diffference i.e one specie is electropositive and the other highly electronegative. The more electropositive specie is metal and it readily loses its valence electrons. The electronegative non-metal gains the electrons and becomes negatively charged. The electrostatic attraction between the metal and non-metals yields the electrovalent bonds.

Your question is not clear but if you can explain yourself i would be glad to .  just trying to : ))
