which image depicts the correct transfer of electrons between sodium and oxygen to form an ionic compound…

Explanation:

Step1: Determine sodium and oxygen valency

Sodium (Na) has 1 valence - electron and oxygen (O) has 6 valence - electrons. Sodium wants to lose 1 electron to achieve a stable noble - gas configuration, and oxygen wants to gain 2 electrons to achieve a stable noble - gas configuration.

Step2: Analyze electron transfer

Two sodium atoms will each transfer 1 electron to one oxygen atom. In Lewis - dot structures, the transfer of electrons is shown by arrows.

Step3: Evaluate options

Option A does not show any electron transfer. Option B shows the correct transfer of one electron from each sodium atom to the oxygen atom. Option C has incorrect arrow placement for electron transfer.

Answer:

B. $\ce{Na}\rightarrow\ddot{\ce{O}}\leftarrow\ce{Na}$
