Which of the following is a key tenet of dalton's atomic theory (click on all that apply)? (1 point) all elements are composed of tiny indivisible particles called atoms. atoms of the same element are identical. the atoms of any one element are different from those of any other element atoms of different elements can physically mix together or can chemically combine to form compounds chemical reactions occur when atoms are separated from each other, joined, or rearranged in a different combination. atomic nuclei contained the negatively charges electrons. atoms retain their identity in a chemical reaction.
