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 ...
Following a classification according to the bonding and ionization properties of the elements, the elements of the periodic table can be classified as:
Alkalines
Alkaline earth
Transition metals
O ...
The periodic table of the elements is the way proposed by Dmitri Mendeléyev in 1869 to arrange the chemical elements, which are ordered by their atomic number, their electron configuration and ...
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 ...
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 ...

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 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 ...
Nonmetals are bad conductors of electricity and heat. They are very weak, so they cannot stretch or become a sheet. They can be solids, liquids or gases, their melting and boiling points being depende ...
