Scientists have observed a never-before-seen form of oxygen, and its behavior could call into question what nuclear physics ...

They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...

This animation will show what the covalent bond between 2 oxygen atoms is like. Narrate the animation by pointing out that: Each oxygen atom has 6 valence electrons in its outer energy level. When the ...

The discovery of this deep-sea oxygen, dubbed "dark oxygen," is the first time scientists have ever observed oxygen being generated without the involvement of organisms and challenges what we know ...

New research challenges a long-held assumption about oxygen in the deep sea, with scientists finding oxygen produced without photosynthesis in the Clarion-Clipperton Zone.

Covalent bonding: Atoms share pairs of valence electrons. For example, in a water molecule (H₂O), each hydrogen atom shares one electron with the oxygen atom, forming covalent bonds.

It’s one of the earliest things you learn in elementary school science class—Earth’s life-sustaining oxygen is produced by plants and algae during photosynthesis using a combination of ...

We think of oxygen as life, sustenance, a literal breath of fresh air. But it's actually a very reactive element. Anyone who's burned a log has witnessed this firsthand. So why do so many life ...
