How do atoms make a molecule;

Two or more atoms held together by a chemical bond to form electrical natural molecules. For example, a molecule of water(H2O) is formed by the combination of two hydrogen H atoms with one oxygen O atom. Organic substances are molecules like proteins, nucleic acid, sugar, carbohydrate, vitamin. Molecules are formed by the combination of hundreds of atoms. Molecules are much bigger than atoms. for example, each molecule of vitamin c (C6H8O6)is made up of 20 atoms.

By changing the position of an atom in a molecule also change the properties of the molecule. If we change the position of these 20 molecules of vitamin and bond them in a different way. It will make a totally different molecule. Millions of molecules existed in the universe before the formation of the earth. The most important molecules that existed from million of years on is carbon dioxide, water, oxygen. Monatomic molecule: The molecule which consists of only one atom is called a monoatomic molecule. They lack a covalent bond. The noble gases ( He, Ne, Ar, Kr, Xe) are monoatomic gases. Is Air is monoatomic gas? The air at room temperature and pressure is the mixture of diatomic gases nitrogen, oxygen. So, the air is diatomic gas not a monoatomic. Diatomic molecule: The molecule consists of two-atom of the same or different elements. The molecule consists of two same atoms is called homonuclear like H2, O2. The molecule consist of two different atoms is called heteronuclear. likeCo, No.

Triatomic particles: The molecule consists of three atoms of the same or different elements. Like, H2O, NH3, O3, etc.

Tetratomic molecule: The molecule consists of four atoms of the same or different elements. Like, As4, P4.Polyatomic molecule: The molecule consist of more than 2 atoms is called a polyatomic molecule. like, ozone, H2O, NH3, etc

. Molecular formula: There are only 100 types of atoms are present but millions and millions of types of thing formed from it. Because all these are made from molecules.
