Water is made from the element hydrogen bonded to the element oxygen. Water molecules are made up of two elements - hydrogen (white atoms) and oxygen (red atoms). Water has a specific ratio of two ...

Chemical biologists, working with small molecules, expand our understanding of these central elements of life. Chemical biologists have differing views of the defining features of our field.

When atoms of two or more elements bond together, they make a compound. These clusters of strongly bonded atoms are called molecules. See how they're represented by two circles of different size ...

But as parts of molecules, they can be used to construct magnetic materials for future components. "In other words, we try to make ordinary chemical elements do things we never thought they could ...

Organometallic molecules, which consist of a metal ion surrounded by a carbon-based framework, are relatively common for early actinide elements like uranium (atomic number 92), but they are ...
