The electronegativity value for Mg is 1.2 and the value for O is 3.5. Based on these values, what type of bond is expected for a compound formed between Mg and O?1. pure covalent

2. ionic

3. polar covalent

4. none of these

5. not enough information

2. Ionic bond

Ionic

Explanation:

In this particular kind of question, we need to understand that the higher the electronegativity value, the more the potential of having an ionic bond formed between the two elements.

Thus, to establish the fact that there should be an ionic bond formation between two elements, we need to know the difference between their electronegativity values. As seen in this question, we can ascertain that the electronegativity difference is quite high. Hence due to this large difference, it is expected that it is an ionic bond that will be formed. If their strengths are comparable, then we can have a covalent bond
