all of the above
question 6 (1 point)
an ionic bond happens when atoms share electrons.
true
false

Explanation:

In a chemical formula, sub - scripts indicate the number of atoms of an element in a molecule. In $CO_2$, C represents carbon and O represents oxygen. The '2' is a sub - script next to O, so it means two oxygen atoms. Also, sharing electrons is characteristic of covalent bonds, not ionic bonds which involve transfer of electrons.

Answer:

For the first question: B. Two oxygen atoms
For the second question: False
