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 ...
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 ...

The noble gases are a group of monoatomic, odorless, colorless chemical elements and have a very low chemical reactivity. Pierre Janssen and Joseph Norman Lockyer were the first to discover, in the 19 ...

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 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 ...
