The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...

But it created byproducts of its own, and one compound has for decades remained mysterious — its formula and structure eluding ... molecular formula: one chlorine atom, two nitrogen atoms ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue examines how atomic structure determines ... configuration of an atom affects its ability ...

“Every bit consists of two positions on a surface of copper atoms, and one chlorine atom that we can slide back and forth between these two positions.” The atom’s position effectively ...

A team of scientists at the Kavli Institute of Nanoscience at Delft University has built a 1kbyte memory in which each bit is represented by the position of a chlorine atom. The storage density of ...

The atomic number of an atom determines which element it is. An element with 17 protons will always be chlorine. However the mass number of the element can vary, which means that it can have ...
