Periodic table by subgroups without symbols (difficult)

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 ...

Periodic table without symbols (difficult)

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 ...

Periodic table, noble gases group without symbols (difficult)

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 ...

Periodic table by SDPF blocks with symbols (easy)

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, alkaline group without symbols (difficult)

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 ...

Periodic table, noble gas group (difficult)

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 ...

Periodic table, actinide group without 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, transition metal group with symbols (difficult)

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 ...

Periodic table, nonmetals group with symbols (difficult)

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 ...

Periodic table, lanthanide group without 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 ...
