Detailed explanation-1: -Expert-Verified Answer. The transfer of electrons is an ionic bond, therefore, we need to determine which substance includes an ionic bond. CO2, is a covalent bond, which is the sharing of electrons, not transfer. KBr, is an ionic bond, because (k) loses an electron to bromine.
Detailed explanation-2: -Ionic Bonds Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
Detailed explanation-3: -KBr is a compound made of the elements potassium and bromine. Both these elements are held together by an ionic bond in the ionic forms.
Detailed explanation-4: -The KBr molecule has an ionic bond. This bond is formed when K transfers its one valence electron to the Br atom. Hence, the ionic bond is formed between K⁺ and Br⁻ ions.
Detailed explanation-5: -(b) Ionic bond is formed by the transfer of electrons from one atom to another.
