can someone explain what the difference here is with an example, like if it goes from a +2 to a +4 what is it considered? oxidation or reduction???? I always get confused on how to know if its oxidation vs reduction.

That's considered oxidation! The way I like to tbhink about it is if the charge was REDUCED then it was REDUCTION

Remember that when an atom gains an electron, its reduction and when it loses electrons its oxidation.

When the charge changes from +2 to +4, that means the atom has lost 2 electrons. Since there is a loss of electrons, this is an example of an oxidation reaction.

oxidation loses electrons so the charge becomes more positive, while reduction gains electrons so the charge becomes more negative

A loss of electrons is oxidation, a gain of electrons is reduction. If the charge increases then electrons were removed so it would be considered oxidation.

Oxidation is the removing of electrons and reduction is the addition of electrons.

OIL RIGS helps me remember that when Oxidation happens it Loses Electrons. When Reduction happens it Gains electrons. It is oxidation because it lost two electrons therefore increasing it's positive charge.

In oxidation, electrons are removed. This means that the charge becomes more positive. In reduction, electrons are added on. This means that the charge will become more negative. This scenario is oxidation because the element became more positive, thus lost electrons.
