Atoms
Gottfried Leibniz
None of the units on the list you provided with the question has any name.
When molecules are broken down into smaller units, they are called atoms. Atoms are the basic building blocks of all matter and cannot be further divided into smaller particles without losing their chemical properties.
Cells
The measure of the quantity of matter in an object is called mass. Mass is commonly measured in units such as kilograms or grams.
the smallest STABLE unit of matter IS an atom
Yes, matter is quantized, meaning it is made up of discrete units called atoms, which in turn are made up of subatomic particles such as protons, neutrons, and electrons. These subatomic particles have quantized properties like energy levels and angular momentum.
Ribosomes
Molecules, and atoms that make up molecules. An atom is made of smaller particles called protons, electrons, and neutrons. Smaller to this are groups such as fermions, Hadrons, Bosons
The smallest units of matter are the subatomic particles.
Thrse molecules are called polymers.
Macromolecules are formed from small units called monomers.
