Size of one atom
WebbHere, we summarize a biological scale to give you a sense of the sizes of different biological objects. Atom An atom is the smallest unit of ordinary matter. Atoms are around 100 picometers (10 −10 m or 0.1 nm) across. Usually, we use 1 angstrom (1Å = 10 −10 m) for the size of an atom. WebbAtoms are tiny and very light. They are made up of sub-atomic particles (protons, neutrons, and electrons), which are even smaller and lighter than an atom. **Size: **Atoms have an average radius of about 0.1 nm. About 5 million hydrogen atoms could fit into a pin head. The nucleus of an atom is 10,000 times smaller than the atom.
