Which formula is used to describe the change in energy of electrons jumping from higher energy levels to lower energy levels

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
