Answer:

2 oxygen ions

Step-by-step explanation

Oxygen is a non-metal with an atomic number of 8. The electronic configuraton of the element is given as:

$O;\text{ }1s^22s^22p^^4$

If a an unknown metal with a charge of 4 combines with oxygen, the required reaction will be:

$M^(4+)+O^(2-)\rightarrow MO_2$

Since oxygen is in group VI of the periodic table and has a oxidation number of -2, to form a neutral compound with charge of +4, this means that 2 oxygen ion will combine with the metal to form a neural compound MO2
