Periodic table, group other metals without symbols (difficult)

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 ...

Periodic table, metalloid group with symbols (difficult)

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 ...

Periodic table, actinide group with symbols (difficult)

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 ...

Periodic table by SDPF blocks without symbols (difficult)

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 ...

Periodic table, lanthanide group with symbols (difficult)

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 ...

Periodic table, alkaline earth group with symbols (difficult)

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 ...

Periodic table, periods 6 and 7 without symbols (difficult)

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 ...
