The fоllоwing lists the five tenets оf Dаlton’s Atomic Theory. 1. All mаtter is composed of extremely smаll particles called atoms.2. Atoms cannot be subdivided, created, or destroyed.3. Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.4. Atoms of different elements can combine in simple whole number ratios to form chemical compounds 5. In chemical reactions, atoms are combined, separated, or rearranged.Which three of the tenets are still accepted by present-day science without modification?
