<u>Answer:</u> The correct statements are ionic bonds form between metal atoms and nonmetal atoms, the less electronegative atoms transfers one or more electrons to the more electronegative atom, the metal atom forms a cation and the nonmetal atom forms an anion and the attraction between ions with an opposite charge forms an ionic bond.
<u>Explanation:</u>
Ionic bond is defined as the bond which is formed when there is complete transfer of electrons from one element to another element. The element which looses electrons is known as electropositive element (less electronegative atom) and the element which gains electrons is known as electronegative element (more electronegative element).
This bond is formed between a metal atom and a non-metal atom.
The metal atom is electropositive in nature and non-metal atom is electronegative in nature.
After loosing electrons, the metal atom forms cations (positively charge species) and after gaining these electrons, the non-metal atom forms anions (negatively charges species)
We know that the oppositely charged species attract each other and thus leads to the formation of ionic bond.
