Answer :
Answer:
Mg and O
Explanation:
To form a bond between oppositely charged particles, the two species must have significant difference in their electronegativity values.
This bond is called an ionic bond and it occurs between a metal and non-metal.
From the given choices Magnesium and Oxygen satisfies the criteria.
Mg is a metal and Oxygen is a non-metal
Mg is electropositive, it will readily lose electrons whereas Oxygen is electronegative and it will readily attract electrons.
