Students will consider why atoms bond to form molecules like H 2 (hydrogen), H 2 O (water), O 2 (oxygen), CH 4 (methane), and CO 2 (carbon dioxide). Objective. Students will be able to explain that ...

A new method uses helium droplets combined with ultrashort laser pulses to trigger chemical reactions in a controlled way.

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

To pull off this new video and showcase what it looks like when water molecules form, the scientists took samples of palladium and placed them into honeycomb-shaped nanoreactors.

So, the hydrogen and helium atoms could form only once the universe cooled down to something like 5,000 degrees Fahrenheit (2,760 degrees Celsius). For historical reasons, ...

Molecules can be thought of as atoms that share electrons. They form electronic bonds that can be visualized like springs, and they jiggle around at a rate that corresponds with the heat energy to ...

Fatty acids are long, linear hydrocarbon molecules with a carboxyl group (COOH) at one end and a methyl group (CH3) at the other, forming a chain of carbon and hydrogen atoms.
