2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and properties. 
3. atoms cannot be divided, created, or destroyed
4. Atoms of different elements combine in simple whole number ratios to form chemical compounds 
5. In chemical reactions, atoms are combined, separated, or rearranged.
So as we can see; the first two sentences are correct while the third sentence not supported in the theory

Answer 2
