A quark is the smallest particle in matter.
An atom is the smallest particle of a substance.
A molecule is the smallest particle of a compound that still retains its properties. An atom is the smallest particle of an element that still retains its properties.
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 iron atom is the smallest iron particle that still has the properties of iron.
A quark is the smallest particle in matter.
An atom is the smallest particle of a substance.
The smallest particle of an element is called an atom.
The atom is the smallest known particle.
The smallest particle in the atom is the electron.
Atoms are NOT the smallest particle- they are the smallest COMPLETE particle. In an atomic reaction, the atoms are broken apart, and release energy.
A molecule is the smallest particle of a compound that still retains its properties. An atom is the smallest particle of an element that still retains its properties.
A Higgs-Boson particle.
An atom is a particle, the smallest particle that can exist by itself.
This particle is called atom.
subatomic particle
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
