Explain Stractually for electrovalent compound

(of bonding) resulting from electrostatic attraction between positive and negative ions; ionic. ... 'The bond that is formed between the two ions is an ionic bond (sometimes also called an electrovalent bond), and the compound produced is an ionic compound.

Explanation:

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
