Which of the following CANNOT occur during a chemical reaction

Well according to Dalton’s theory atoms of the same element are alike in all respects and atoms of different elements are different. So elements can be combined to make a new element but can not be the same element. It’s kinda hard to explain but essentially if it’s the same then it will stay the same and if it’s different then it will stay different. It can’t change in that regard but it can be combined to create anew.
