In chemistry, a molecule is defined as a sufficiently stable electrically neutral group of at least two atoms in a definite arrangement held together by very strong chemical bonds. It can also be defined as a unit of two or more atoms held together by covalent bonds.
There are two atoms of Hydrogen in the molecule.
a molecule
2 Oxygen atoms
Two atoms or more make a molecule. Normally, the atoms are bonded in a covalent bond or some other chemical bond.
If I undersstand your question correctly, a group of atoms that is joined by a covalent bond, and is neutral would be called a non-polar molecule.
It makes a molecule.
A molecule is a combination of atoms. To know how many atoms are in one molecule, you have to find out what atoms are in the molecule.
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
A combination of different kinds of atoms make up a molecule for example H2O means two atoms of hydrogen and one of oxygen.
Molecule of nitrogen has 3 atoms of nitrogen. Nitrogen molecule exist as N3.
The oxygen that we breathe has 2 oxygen atoms in each molecule. Ozone has 3 oxygen atoms in each molecule which makes it a more powerfully oxidizing form, decaying to normal O2 in the process.
Two or more different kinds of atoms chemically combine to form a compound. The atoms make a molecule of that compound, which is the smallest individual component (part or piece) of that substance.P.S. That makes the answer Molecule.
