The number of electrons lost or gained by an atom to get stable electronic configuration in forming ionic bond is called its electrovalency.
When one atom transfers one or more electrons to another atom, it forms an electrovalent bond.
Na has electronic configuration of 2,8,1. Loss of outermost electron is necessary to complete the octet. Cl has electronic configuration 2,8,7. In order to complete its octet it needs to gain an electron. Na transfers its outermost electron to Cl forming an ionic or electrovalent bond.
