Which type of bond results when one or more valence electrons are transferred from one atom to another?

Electrovalent or ionic bond

Explanation:

For atoms to enter into chemical bonding, they either share, give or receive electrons. When they share electrons, it is a case of covalent bonding. A situation in which they give or take electrons is principally an electrovalent bonding case.

Thus, the type of bond resulting from the transfer of electrons between valence shells of atoms is what we know as electrovalent or ionic bonding. It usually occurs between atoms which have a high value of electronegativity value difference between the atoms such as a case of sodium and chlorine
