How big is a atom? An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers (1×1010 m, a ten-millionth of a millimeter, or 1/254,000,000 of an inch).

What is the charge of an atom? An atom consists of a positively charged nucleus surrounded by one or more negatively charged particles called electrons. The number of protons found in the nucleus equals the number of electrons that surround it, giving theatom a neutral charge (neutrons have zero charge).
