When atoms get an electric charge, they act very differently. Now called ions, these are behind many aspects of chemistry, including acids and batteries.
In chemistry, this attachment between atoms forms because of the power of attraction. Chemical bonds make up every solid object on Earth.
This oxygen-making experiment shows that astronauts could one day make air to breathe and to help fuel their ride back home.
When various particles, atoms, ions or molecules come together to form a substance, they are held together with chemical bonds.
Acids give away particles with positive charge. Bases accept positively charged particles. They are both critical for chemical reactions.
The catalyst is an improvement over its predecessors. Made of cheap materials like iron, it produces jet fuel in a single step.
Baking soda volcanoes are a fun demonstration, and with a few tweaks they can be an experiment, too
New measurements of a weird but simple atom, one without a nucleus, suggest it may have unexpected properties. Scientists find this troubling.
Need water but you have no access to rain, lakes or groundwater? Materials known as metal-organic frameworks could be used to slurp that water from the air, new data show.
