Covalent bonds form when two elements share electrons to make a complete outer shell of electrons. Ionic bonds form when one element donates one or more electrons to another element to make a complete outer shell of electrons. Which statement best explains the type of bond that will form between two elements from group 6A in the model?
A

The two elements will form a covalent bond because both elements will share a single electron in order to have full outer shells.

B

The two elements will form a covalent bond because both elements will share a pair of electrons in order to have full outer shells.

C

The two elements will form an ionic bond because one of the elements will donate one electron to the other element in order to have full outer shells.

D

The two elements will form an ionic bond because one of the elements will donate two electrons to the other element in order to have full outer shells.
