The smallest of the permanent core particles of an atom is the electron. Its mass is about 1/1836 of the mass of a hydrogen atom. The actual mass of the electron is 9.1085 × 10 −28 g or 9.1093 × 10 −31 kg. The mass of the electron is often ignored because this mass is too small. Electrons always provide a negative charge.
Atom – Wikipedia
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics—as if they were tennis balls, for example—is not possible due to quantum effects.
