Detailed explanation-1: -The correct answer is (2) ionic bond. An ionic bond is a type of chemical bond that forms when an electron is transferred from one atom to another. This completes the valence shell of both atoms, making them more stable.
Detailed explanation-2: -An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation-a positively charged ion.
Detailed explanation-3: -An iodine atom is expected to gain an electron when forming an ion due to its relatively high electron affinity. It needs only one more valence electron to have an electron configuration analogous to that of a noble gas, making it more stable. When it accepts an electron, it will become the iodide ion (I− ).
Detailed explanation-4: -The iodine and bromine atoms each share one electron with the other. Through sharing, the iodine atom now has access to eight valence electrons, as does the bromine atom.
