Dalton’s Atomic Theory states these things: 5 pointsCheck

What is: 1) All elements are composed of tiny individual particles called atoms. 2) Atoms of same element are identical and different from those of other elements. 3) Atoms of different elements can physically mix or chemically combine in whole number ratios. 4) Chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element are never changed into atoms of another element in a chemical reaction. 5 points Back to Category Slide
