The modern periodic table was created by Dmitri Mendeleev in 1869. He arranged the elements based on increasing atomic mass and similar chemical properties. Mendeleev's table provided a framework for organizing the known elements and predicting the properties of undiscovered elements.
Element number 113 (Nihonium) can be found in group 13 and period 6 of the modern periodic table. It is a synthetic element created in a laboratory and is highly reactive due to its configuration of valence electrons.
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
The modern name of Eka Boron is Francium. It is a highly radioactive element with the symbol Fr and atomic number 87 in the periodic table.
No. In the modern periodic table, silicon (element 14) is a metalloid in group 14.Group 14 was previously known as "group IV" (A or B).

Eka-aluminum corresponds to the element gallium on the modern periodic table. Eka-aluminum was a placeholder name given by Dmitri Mendeleev for an element that he predicted would have properties similar to aluminum but with a higher atomic mass. Gallium, discovered in 1875, fits these properties and is known as eka-aluminum's modern counterpart.
Argon is in the third period of the modern periodic table.

Ir refers to iridium element that is placed in group-9 and period-6 in the modern periodic table.
