It depends whether it can exist alone or has a pair. Some atoms have semi-filled outer shells of electrons (sub-atomic particles) and therefore need to be covalently bonded with another molecule in order to be stable. Others can exist alone.
Yes, the notation of H2 indicates a single molecule of two bonded hydrogen atoms.
A particle composed of one or more atoms is called a molecule
No, a single atom is not considered a molecule. A molecule is made up of two or more atoms bonded together.
Two atoms are contained a single diatomic molecule. Elemental Hydrogen is an example of this where two hydrogen atoms share their only electrons in a single covalent bond.
No. Molecules consist of at least two atoms. O2 is a molecule.
covalent bonding
No, a single atom of gold is not a molecule. A molecule is a group of atoms bonded together, while an atom is the smallest unit of an element. So a single atom of gold is just that - a single gold atom.
the smallest atom is hydrogen, the smallest molecule would be the naturally occurring diatomic hydrogen.
One molecule of water contains two atoms of Hydrogen and one atom of Oxygen, which is why its formula is H2O.
The definition of a molecule is two or more atoms which have chemically combined to form a single species. Therefore when the two hydrogen atoms combine with the one oxygen atom, you get a single substance.
No, a particle is not considered a molecule. A molecule is made up of two or more atoms bonded together, while a particle can refer to a single atom or a group of atoms.
