Alkali metals
The elements that are found on the left side of the periodic table are alkali metals.
Atoms to the left on the periodic table Atoms with a large atomic radius
The periodic table of elements is the arrangement of elements according to atomic number increasing from left to right across rows of the table.
In general, the elements with higher atomic numbers are the most radioactive and they are found at the bottom of the Periodic Table of Elements
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
On the periodic table metals are listed on the left side.
He listed the elements in his periodic table in groups in which he saw patterns. He left gaps where he thought elements had not yet discovered. Hope this helps :p

Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
All known elements are listed on the periodic table of the elements. Historical tables did not have elements listed that were unknown at the time. For instance, Dimitri Mendeleev, who laid out the first successful periodic table in 1869, did not have any of the noble gases listed since none of them had been discovered at that time. Modern periodic tables have gaps at the lower right end where elements are expected to be created in labs in the future, but have not been successfully created yet.
The atomic number is the number located in the upper left corner of the element on the periodic table. Elements are listed in order of increasing atomic number.
The metals in the lower left corner of the periodic table are the least electronegative.

Element name is listed in the center.Element atomic number on the top left.Element atomic mass on bottom left.
The periodic table of elements is the arrangement of elements according to atomic number increasing from left to right across rows of the table.
On the left of the periodic table, especially group 1 and group 2 elements.
Elements on the left side of the Periodic Table are "Alkali Metals". There is also one non-metal element. H(hydrogen)
