4 concepts of Dalton's atomic theory and their correctness - 1. All matter is composed of indivisible particles (atoms) (can split atoms but this is generally correct) 2. atoms and indestructible and unchangeable (can change with extraneous outside methods, but still true) 3. all atoms of a given element are identical (false because of isotopes) 4. compounds are formed when atoms of different elements combine (true) absolute numbers - counts rather than measurements, conversion factors; i...
