Answer: Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction.
Explanation:
Dalton's Atomic Theory was proposed in the 20th century by an English Scientist named John Dalton. His theory is postulated as follows:
1) All elements are composed of tiny indivisible particles called atoms.
2) The atoms of any one element are identical to those of any other element. 3) Atoms of different elements can physically mix together or can chemically combine in simple whole-number ratios to form compounds.
However, the final option is NOT one of Dalton's Theory

Answer:
D
Explanation:
Lithium has one valence electron, so it has one to give away to have an outer shell of 8.
Sulfur has 6 valence electrons, so it needs 2 to get an outer shell of 8.
If we have two Li, that means sulfur will get 2 e- and Li will give away 2 e-, so the formula is Li₂S.
The energy that is lost becomes free energy.
