it is arranged in the increasing order of atomic number.
The periodic table organizes the elements by atomic number (number of nuclear protons).
Atomic number
The current Periodic Table is organized by each elements atomic number. The atomic number is the number of protons in the nucleus of the atom of each element.
number of protons
Atomic number was not used by Mendeleev to organize his periodic table. He organized the elements based on their atomic mass and properties, leaving gaps for undiscovered elements that were later filled.
They used atomic number instead of Atomic Mass to organize the elements
Atomic mass was used to organize the earliest periodic table.
They used atomic number instead of Atomic Mass to organize the elements.
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
The atomic number of permanganate on the periodic table is 25.
The atomic number of scandium on the periodic table is 21.
The atomic number of uranium on the periodic table is 92.
