Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.
Atoms cannot be subdivided, created, or destroyed.
Atoms of different elements can combine in simple whole number ratios to form chemical compounds.
In chemical reactions, atoms are combined, separated, or rearranged.
Each atom is uniform, homogeneous, colorless, tasteless, and indivisible.ll atoms of a given element are identical in mass and properties. Compounds are formed by a combination of two or more different kinds of atoms. A chemical reaction is a rearrangement of atom.
