Either an atom or a molecule, depending on the substance.
The smallest particle of an element is called an atom.
The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is called a molecule. Each molecule is made up of one or more atoms chemically bonded together.
The smallest particle of a substance that still retains all the chemical properties of that substance is called a molecule. In the case of elements, the smallest particle is an atom, which retains the unique properties of that element. Molecules are made up of atoms bonded together in specific arrangements that determine the chemical behavior of the substance. Therefore, the smallest particle of a substance that is still that substance does indeed possess all the properties of that substance.
Democritus, the ancient Greek philosopher, was the first scientist to propose the concept of atoms as the smallest particle in the universe. He believed that all matter was made up of indivisible and indestructible particles called atoms.
A quark is the smallest particle in matter.
This particle is called atom.
A substance that is composed of only one kind of matter is called an element. The smallest particle of an element is called an atom.
There are two definitions that can answer particulate identity at its singular unit. If the given is a pure element, the smallest particle retaining identity would be the individual atom (or diatomic molecule in some gases as in O2). If the substance is a molecular compound such as water, its smallest identifying unit would be a single H20 molecule.
The smallest size of sediment particle is called clay. Clay particles are smaller than 0.002 mm in diameter.
The smallest particle of an element that has the properties of that element is called an atom.
This particle is the atom.
The smallest particle of matter is called an atom. It is the basic unit of a chemical element and retains the properties of that element.
