answer
All matter is made up of particles that are too small to see
question
the smallest particle of a pure substance that has the properties of that substance and is capable of a stable independent existence
answer
molecule
question
1). All matter is made up of tiny particles called atoms 2). Substances called elements are made up of atoms that are all identical 3). Substances called compounds are combinations of atoms of two or more elements 4). Every molecule of a specific compound always contains the same number of atoms of each kind of element found in the compound 5). In chemical reactions, atoms are rearranged, separated, or combined, but are never created nor destroyed
answer
