[SOLVED] Is it the protons or electrons that are responsible for an element's propert
On a chemistry test I took, there was a question that asked "What subatomic particle is responsible for an element's physical and chemical properties"?
I picked the "proton" as the answer choice, but the teacher's answer is "electron"
I do not see why her answer is correct, not saying that I'm right. I understand that the electron, valence electrons respectively, are responsible for chemical reactivity. But what about physical? Since the number of protons also determine the number of electrons, the protons should be considered when it comes to elements physical and chemical properties. Physical, besides appearance, would be like boiling point and melting point and how can those properties be based on the number of electrons? the electrons are only responsible for chemical reactivity, right? If you know any sources, please cite them...
Thanks
