Why does an ionic bond transfer electrons instead of sharing?

When there is a whole transfer of valence electron between the atoms is called an ionic bond. In this type of bond construction, the atoms get contrarily charged.

The ionic bonds are formed due to electronegativity. According to Pauling, the capability of an atom to draw electrons towards itself is called electronegativity.

When there is a huge contrast in electronegativity between the atoms, the electrons are completely transferred between the atoms.

The atom that relinquishes an electron are called a cation and is positive whereas the atom that acquires an electron are called anions and are negatively charged.

Therefore, due to electronegativity, ionic bonds are formed.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

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.
