Answer:
C. Na and F
Step-by-step explanation:
The reaction between Sodium and fluorine will proceed more quickly and easily of all the given reaction choices.
This is because fluorine is the most electronegative element and sodium is more electropositive when compared to Lithium.
- This significantly large electronegativity difference between the atoms confers a high reactivity on both of them.
- In this reaction, an ionic bond forms by the virtue of sodium losing one electron to be gained by fluorine.
- This way both atoms becomes isoelectronic with Neon.
