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 other metals are located between transition metals and semimetals. Sometimes known as block metals or poor metals, they tend to be soft and have low melting points, in addition to having greater e ...
Following a classification according to the bonding and ionization properties of the elements, the elements of the periodic table can be classified as:

Currently, the periodic table is organized and subdivided into four blocks depending on the last orbital of the electronic configuration. These blocks are called:
Block s: in these elements the most ...
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 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 ...
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 ...
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 ...
