This video excerpt from NOVA's "Hunting the Elements" explains why some elements are more reactive than others.

Now that we have examined many of the factors that affect accuracy and precision, we will categorize the types of errors that result from said factors, as well as mentioning other, practical ...

Specifically, we investigated the behavior of uranium's so-called 5f electrons—electrons that, despite being located in the inner shells, play a crucial role in the element's chemical properties.

GitHub’s Electron is rapidly gaining popularity for building cross-platform applications. An open source application shell for apps built using Web technologies, Electron is a spin-off of GitHub ...

For example, C stands for carbon, O stands for oxygen, S stands for sulfur and Na stands for sodium. For a molecule, we use the chemical symbols of the atoms it contains to write down its formula.

Sometimes, we learn things early on in life, and simply accept that's how the world works. Drop a chunk of pure sodium in water, for example, and the reaction is legendary in its violence. As soon ...

Microsoft released its first cross-platform code editor to great fanfare yesterday, but it’s not quite what it appears when you peek under the hood. Visual Studio Code is based on technology ...

The shell ultrastructure of the gastropod Cittarium pica (L.) (Recent; Bimini, Bahamas) has been studied by means of correlated light and scanning electron microscopy of growth surfaces, fracture ...

Just over two years after building an 8-Megajoule railgun, the branch has penned two $7 million checks to defense contractors Boeing and Raytheon for the design and development of a free-electron ...
