what sorts of elements can we see in it?
Nonmetallic elements such as metalloids,  groups of families of elements and elements having metallic lustre.
Periodic table
s of elements; groups and periods; and periodic table blocks. While the recognition of metals as solid, fusible and generally malleable substances dates from antiquity, Antoine Lavoisier may have the first to formally distinguish between metals and nonmetals "('non-métalliques')" in 1789 with the publication of his 'revolutionary' "Elementary Treatise on Chemistry". In 1811, Berzelius referred to nonmetallic elements as metalloids, in reference to their ability to form oxyanions. In 1825, in a revised German edition of his "Textbook of Chemistry," he subdivided the metalloids into three classes. These were: constantly gaseous 'gazolyta' (hydrogen, nitrogen, oxygen); real metalloids (sulfur, phosphorus, carbon, boron, silicon); and salt-forming 'halogenia' (fluorine, chlorine, bromine, iodine). Only recently, since the mid-20th century, has the term metalloid been widely used to refer to elements with intermediate or borderline properties between metals and nonmetals. Mendeleev publishe
what is the basis of arranging the elements in the modern periodic table Atomic number, electron configuration, and recurring chemical properties. what is the purpose of the table? UNANSWERABLE why is called so? Because of the tabular display of the chemical elements.

In chronological order, this section discusses metals and nonmetals (and metalloids); categories of elements; groups and periods; and periodic table blocks.
