Elements and Compounds: Understanding elements and compounds is basic knowledge to study chemistry. Elements are the basic building blocks of matter, while compounds are substances formed when two or ...

Helium, the gas that fills up our balloons, has a reputation as a chemistry lightweight—as an element that doesn’t react with much of anything. Researchers say they’ve used high pressure to coax ...

Analysis of organic compounds -- called polycyclic aromatic hydrocarbons (PAHs) -- extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas ...

THE clathrate type of molecular compound is formed by the imprisonment of one sort of molecule in some kind of cage structure of the other component. In the compound the molecular component M is ...

Chemical reactions occur when elements or compounds combine and create new compounds. Elements are substances that contain only one type of atom and are represented by unique symbols on the periodic ...

Scientists have coaxed one of the universe’s most stubborn elements into a new compound. Formed under intense pressures, the newly discovered compound packs helium atoms into crystalline iron, ...
