water
The atom is the smallest known particle.
subatomic particle
H - Hydrogen Smallest particle with formula H2O is water molecule and is composed of two atoms of hydrogen and one that of oxygen. two atoms of hydrogen incidentally combined to make one hydrogen molecule. Thanks, Dilip Thakur
Well, water (H2O) does exist as molecules, which are the smallest representative particles of water. However, neon (Ne) is an element, which means its smallest representative particle is the atom.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.
A quark is the smallest particle in matter.
molecule
An atom is the smallest particle of a substance.
This is the molecule of water - H2O.
The smallest particle of an element is called an atom.
The atom is the smallest known particle.
If you mean the smallest particle of water that has the properties of water, then yes, water particles are molecules.
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.
