Dalton's atomic theory taught that all matter composed of atoms (inseparable and cannot be destroyed).

Explanation:

Dalton's atomic theory, the initiative comprehensive approach to explain all matter based on atoms and its properties. He proposed this theory based on the law of mass conservation and constant composition law. The importance of Dalton's atomic theory are:

Everything consists of atoms, which are inseparable elements of matter and cannot be impaired. All element's atoms are identical. Atoms of different elements differ in their sizes and masses. Compounds are created by simply bonding atoms and creating complex atoms (molecules).

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
