That would be an atom. Atoms go down to protons, neutrons and electrons, but these do not have unique characteristics. So, the smallest particle with unique characteristics is an atom.
cells
an atom Actually, the smallest unit of matter is called a Quark. Quarks combine to form protons and neutrons, which are the core of an atom.
the basic structural unit of living matter is THE ATOM
An atom.
When you consider the composition of living and non living things, both can be broken down into what comprises them. If one considers non-living matter, then "particle" may be used to describe the smallest unit. As knowledge advances, a "particle" by definition has evolved i.e., quarks being the smallest "particle" of an atom whereas for years it was thought that the atom was the smallest unit of matter. Conversely, the cell is considered the smallest unit of organic (living) matter The only major difference between them is that a cell is the smallest particle of a living object and a molecule (made up of atoms) is the smallest unit of a nonliving object.
The phase of matter, whether solid, liquid, or gas, is dependent upon temperature. Atoms are the smallest unit of matter that have consistent chemical characteristics, which would include the melting or freezing point, so if we are talking about liquids, we would have to use the atom as the smallest unit.
An atom of that element has all the properties of that element.
This smallest unit of matter is the atom.
The smallest unit of a chemical element is the iron.
The smallest unit of matter is an atom, which is made up of protons, neutrons, and electrons. Protons and neutrons are made up of quarks, while electrons are thought to be fundamental particles.

The molecule.
Smallest unit of matter that is indivisible.
That would be AN ATOM.

SI stands for Systems International. The unit for matter is kilograms. This unit can be used to describe the largest amount of matter to the smallest amount.
