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 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 ...
