The stunning estimate offers hope that natural ecosystems in pan-tropical forests could help humans control global warming.

Any chemist could talk for days about carbon. It is after all an everyday, run-of-the-mill, found-in-pretty-much-everything, ubiquitous element for us carbon-based life forms. An entire branch of ...

"The metal is found combined in practically all rocks, sand, clay, and other soils." Scientists discover game-changing ...

The periodic table captures a subtle pattern that runs ... If you have 12 protons, that’s carbon. As you keep adding protons, you find that similar properties recur in every 8th element.

The position of an element on the periodic table provides information about its ... Diamond is a form of carbon. Carbon is a non-metal. In the form of diamond it has a high melting point and ...

These are almost one-quarter of the periodic table and are mainly found in the first four periods. Of these, 11 are essential elements that our bodies need in larger amounts: oxygen, carbon ...

Keeping up with the neighbours is rarely a concern in the periodic table. Nitrogen doesn't care much what carbon and oxygen are up to, and rarely casts covetous glances at phosphorous. But there's at ...
