The difference between an ionic bond and a covalent bond is that

Select one:

a. ionic bonds commonly occur between two metals and covalent bonds occur between metals and nonmetals.

b. ionic bonds are between atoms that can share electrons; covalent bonds are between atoms that will donate/accept electrons.

c. covalent bonds come about because of a sharing of electrons; ionic bonds do not.

d. ionic bonds are between smaller atoms; covalent bonds are between large atoms.

Answer #1

A covalent bond is formed by mutual sharing of electrons while ionic bond is formed when one atom loose electrons and others gain it and then there's electrostatic force of attraction between them.

A. This isn't true for ionic bond as metals have the tendency to lose electrons so there can't be ionic bond between them.

B. As covalent bond is formed by mutual sharing of electrons rather than sharing so this isn't true also.

C. This one is true as there's mutual sharing of electrons in covalent compounds and ionic bonds don't have mutual sharing.

D. This isn't true. As longer we've two atoms one of which can donate electrons and others can gain there is probability of formation of ionic bond irrespective of their size.

So correct answer is C.
