It is an atom.
An atom is the smallest particle of an element that still has the chemical characteristics of that element
An Atom
A molecule.
The smallest part of any chemical element that can exist is an atom of that element. The smallest part of a chemical compound that can exist is a molecule of that compound.
is the smallest particle of an element that has the properties of that element
The smallest particle of an element is called an atom.
An atom is the smallest particle of an element that still has the chemical characteristics of that element
Either an atom or a molecule, depending on the substance.
a quark or if you mean the smallest element hydrogen
This particle is the atom.
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
An atom is the smallest particle that is still recognisably the element
The smallest particle in the atom is the electron.
is the smallest indivisible particle which can exists on its own eg. an atom of fluorine.
The smallest particle of an element that has the properties of that element is called an atom.
Atom
The smallest particle of an element would be an atom. Any smaller and it would not be an element, but something more basic. Atoms are made of Protons, Neutrons, and Electrons. Protons and Neutrons are made of Quarks, Leptons, and Bosons.
