A dalton is the same as an atomic mass unit. And an atomic mass unit is approximately the mass of a nucleon (proton or neutron) such that the mass is 1 g/mol. So in this problem you have 15 protons and 16 neutrons, so the number of daltons is 15 + 16 = 31.

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
