Carbon is made up of just one type of atom close atomThe smallest particle of an element. We often think of atoms as tiny spheres, but in fact they are made from smaller particles called protons ...

It might not be flashy, but it's an essential part of the atmosphere's chemical composition. Though present in a small fraction, carbon dioxide punches above its weight in importance. It's a major ...

An element’s chemical symbol is a single capital letter or a capital letter followed by a lower case letter. What is carbon? Find out about the structure and properties of the element carbon.

Silicon (Si) is a metalloid, element number 14 on the periodic table. Like carbon, silicon has four bonding sites, but silicon is more than twice as heavy as carbon. The high melting point of ...

When cosmic rays reach Earth’s upper atmosphere, physical and chemical interactions form the radioactive isotope carbon-14. Living organisms absorb this carbon-14 into their tissue. Once they die, the ...

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 ...

the body replaces the oxygen in the blood stream with carbon monoxide, leading to vital organs being deprived of oxygen. The chemical is produced from the incomplete burning of natural gas or ...

Using a chemical reaction inspired by rocket fuel ignition, Cornell researchers have engineered a nanoporous carbon with the highest surface area ever reported, a breakthrough that is already ...
