In the periodic table of the elements, each row of the table is called the period. The number of levels an atom has determines the period to which it belongs.
The periodic table of the elements is the ...
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 ...

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 ...
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 ...
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 ...
Actinides are also known as "internal transition elements." They have radioactive properties and are extremely unstable, having a very short half-life. Within the periodic table, they are us ...
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 ...
