The transition metals are located in the central part of the periodic table. The name "transition" comes from a characteristic that these elements have to be able to be stable by themselves ...
Semimetals, also known as metalloids, share properties of both metals and nonmetals. Metallic in their appearance, they can be both bright and opaque with an easily modifiable shape but they are not g ...

Halogens (from the Greek, salt-forming) are very useful elements since, as the name implies, they form salts when they react with metals. Without the halogens we would not have sodium chloride, better ...
Lanthanides are a group of elements also called "rare earths" because they are in the form of oxides. They form the "internal transition elements" next to the actinides, with which ...

The alkaline earths take their name from the one who received their oxides, "earths", which have alkaline properties. They are harder than alkali metals, have shine and are good electrical c ...
Alkalines are named because they produce strong bases (or alkalis) that neutralize acids after reacting with water. They are of very low density and good conductors of heat and electricity. They are n ...
