Excerpt from The Elements Chemical Arithmetic: A Short System of Elementary Qualitative Analysis
A mass of matter is any portion of matter appreciable by the senses.
A molecule 18 the smallest particle of matter into which a body can be divided without losing its identity or it is the smallest portion of matter which can exist by itself.
An atom is a still smaller particle produced by the division of a molecule; or it is the smallest portion of matter that can go into combination.
Examples. The sun and a grain of sand are masses of matter. The smallest particle of salt which can exist and which exhibits the properties of salt is a molecule. The minute particles of chlorine and sodium which com pose the molecule Oi salt are atoms.
A mass is made up of molecules, and a molecule is com posed of atoms.
