B. two sodium atoms
C. two oxygen atoms
D fluorine and chlorine

sodium and bromine

Explanation:

The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.

Which two atoms form an ionic bond?

Answer : A

Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).

Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.

Thus, the correct answer is option (C).
