You've flipped arguments. You first told me it was that quantity exisited in the universe, but it was not immaterial. Now it's that quantity only exits in the mind (concept). However, lets assume that this why I'm wrong and ignore the flip flop.
If quantity exists apart from our minds, the reactions of atoms/compounds exist because of quantitative factors (namely the electromagnetic forces) making the situation as it is taught today.
However, if quantity is just a concept, the reactions (outside of my head) are not based on quantity. Instead, quantity is just how our brains make sense of the reactions. Therefore, there are no electromagnetic forces in the world because force is quantitative.
Both options are actually valid, but the latter destroys science and ends you with at least Humean styled skepticism.

The Lord bless you and keep you; the Lord make his face to shine upon you and be gracious to you; the Lord lift up his countenance upon you and give you peace.
