Atoms with greatly different electronegativity values are expected to form
A)no bonds
B)covalent bonds
C)triple bonds
D)ionic bonds
E)none of these

Question

Quizplus · Accepted Answer

Atoms with greatly different electronegativity values (usually more than 1.7 difference) are expected to form ionic bonds, as one atom will donate an electron to the other to form a positively charged cation and a negatively charged anion, which are held together by electrostatic attraction. Covalent bonds are formed by atoms with similar electronegativity values sharing electrons, while triple bonds are a type of covalent bond characterized by sharing three pairs of electrons. Thus, the best choice is ionic bonds (D).
