The transfer of electron from an atom of _ I.E to other atom with _ E.A is called ionic bond by Lewis:

Explanation

Option C is correct.The transfer of an electron from an atom with a low ionization energy (IE) to an atom with a high electron affinity (EA) is called an ionic bond. An atom with a low ionization energy is easily able to lose an electron. This is because the valence electrons in the atom are not held very tightly to the nucleus. An atom with a high electron affinity is easily able to gain an electron. This is because the atom has a strong attraction for electrons. When an atom with a low ionization energy loses an electron, it becomes a positively charged ion. This ion is called a cation. When an atom with a high electron affinity gains an electron, it becomes a negatively charged ion. This ion is called an anion. The cation and anion are attracted to each other by the electrostatic force between their opposite charges. This force holds the ions together in an ionic bond. Ionic bonds are found in many common compounds, such as sodium chloride (NaCl), magnesium oxide (MgO), and calcium carbonate (CaCO3).
