The most reactive non-metal is fluorine, and it is also the most reactive element that scientists have discovered. Fluorine combines readily with almost any substance, including metals that are usually stable. More »

The most reactive group of metals on the periodic table are the alkali metals. These metals are so reactive that they are not found naturally by themselves; they are found in nature as parts of compounds. More »

The most reactive metal in the periodic table is francium. Francium belongs to the alkali metals, a group on the periodic table whose members are all highly reactive. These metals are highly reactive because they all hav... More »

All acids contain the element hydrogen. When an acid is dissolved in water, it releases hydrogen ions, which combine with water molecules to form hydronium ions, H3O+. More »

The Bohr model for potassium contains 5 concentric circles with the element's number of protons and neutrons written in the center. Each circle after that represents an energy level, with dots indicating electrons. There... More »

Magnesium conducts electricity, mainly because it is a metallic element. Other similar metals that also conduct electricity are sodium and aluminum. More »

The reaction between a metal oxide and an acid produces a salt and water. The resulting mixture is warm. The kind of salt produced is dependent on the specific acid used. More »
