One of the rarest and most mysterious elements in the periodic table has finally given up some crucial chemical secrets, eight decades after its discovery. Researchers at Oak Ridge National Laboratory ...

Sodium is in group 1. A sodium atom has one electron in its outer shell. The atom is more stable if it has a full outer shell. A sodium atom can lose its outer electron. It will still have 11 positive ...

Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

Protons (H ＋) are typically the carrier in hydrogen ion conduction. Numerous H ＋ conductors have been developed in a variety of systems, including oxides, polymers, and solid acids. Through the cation ...

The group 1 elements react quickly with oxygen in the air at room temperature. Most transition elements react slowly, or not at all, with oxygen at room temperature. Some transition metals react with ...
