Why electrovalent bond is also known as ionic bond?

Answer 1

Compounds with electrovalent bonds consist of charged particles called ions, which are held together by mutual electrostatic attraction. (The term "ionic bond" is more common, at least in the USA, than "electrovalent bond.")

Answer 2

If the electrons in a bond are perfectly shared that is called a covalent bond. If one atom completely rips off the electron that is called an ionic bond. Neither happens in reality. All bonds are somewhere between those extremes. So the terms "covalent" and "ionic" mean something like "over here" and "over there".

Answer 3

The terms "electrovalent bond" and "ionic bond" are used interchangeably because they both refer to the same type of bond formed between atoms through the transfer of electrons. In an electrovalent bond, one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces.
