Various signs of this include: 1  Canon Foreigner: Adding a new character, often to play the role of The Watson in the adaptation of a book with a lot of dense exposition. 2  Composite Character: Combining character roles (and subsequently enlarging the role of one character) to make a simpler narrative to follow.
A molecule is two or more atoms chemically joined together. If at least two different elements make up the molecule, it is called a compound. For example, hydrogen gas (H2) and water (H2O) are molecules, but water is also a compound because it is made up of hydrogen and oxygen.f at least two different elements make up the molecule, it is called a compound.

Mixtures are substances composed of two or more components physically blended. When two or more similar kinds of atoms bind, they form an isotope. A molecule contains two or more atoms. Protons, neutrons, and electrons comprise atoms, which chemically bond with other atoms to form molecules.
