An atom.
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
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.
In digital imaging, a pixel is a single point in a raster image, or the smallest addressable screen element in a display device; it is the smallest unit of picture that can be represented or controlled
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.
The smallest unit of a chemical element is the iron.
The smallest unit of Matter that retains the property of an element is the atom.
An atom of that element has all the properties of that element.
The smallest unit in an element is the atom.
The smallest identifiable unit of an element that retains the properties of the element is an atom.
The Atom is the smallest particle of an element that has characteristics of that element. The Atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element into a Atom.
The smallest unit of Matter that retains the property of an element is the atom.
The smallest unit of an element that maintains the properties of that element is the atom.
The atom is the smallest unit of an element that has all the properties of the element.
The smallest unit of an element that is still that element is an atom. Some elements normally exist as molecules, but under some circumstances these can be broken down to individual atoms.
The smallest unit of a chemical element is the atom.
Atom is the smallest unit of matter which combines to form elements, compounds and mixtures.
