And that’s it! Nearly everything in this room, in your room, and in the entire universe, is made of: elements with one kind of atom, compounds containing different types of atoms chemically ...

The atoms of other elements, however, like hydrogen, join with another hydrogen atom as a pair, making a molecule. So, all compounds are molecules, and some elements are too. All the different ...

The transplutonium actinides are highly radioactive and rare, making them difficult to study. To examine their chemical ...

More than 75 years after its initial discovery, scientists have created an organometallic molecule containing the ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

What are Endangered & Critical Elements? Of the 118 elements that make up everything—from the compounds in a chemist’s arsenal to consumer products on the shelf—44 will face supply limitations in the ...

Inorganic chemistry is the study of the structure, properties and reactions of all chemical elements and compounds except for organic compounds (hydrocarbons and their derivatives). Chemical ...

Organometallic chemistry is the study of the synthesis, structure and reactivity of chemical compounds that contain metal-carbon bonds. These compounds are often used as homogeneous catalysts.

Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur). Originally limited to the ...

Carbon, with its myriad compounds, is the backbone of life and the central element of organic chemistry. The number of bonds a carbon atom forms with other elements in a compound determines its ...
