This can lead to a family of similar molecules being formed.

Some elements form molecules of more than one size.

When they are combined with each other, they can form molecules.

If the atoms do not form molecules, the reaction will definitely require energy overall.

This means that some other solar systems might have the potential to form more complex molecules (or do so faster) than ours.

When they stick together they form molecules, and that's chemistry.

Also, Carbon is the only element that can form long chain-shaped molecules.

However, if the product atoms form molecules, energy will be liberated to the environment as the bonds are formed.

Theoretical chemistry predicts what happens when atoms combine to form molecules.

During this process these dyes form complex larger molecules which is the basis of their good wash-fastness.
