Structure of an Atom
... Atoms of a given element are identical but differ from the atoms of other elements. Atoms cannot be subdivided, created, or destroyed. Atoms of different elements combine in simple whole-number ratios to form chemical compounds. Atoms take part in all chemical reactions. According to Dalton’s atom ...
