The atomic weight, or the number of protons.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
The elements arranged according to their atomic number in the table are called periodic table.
The amount of electrons in each element.
Element's atomic number decide its place in periodic table. They r arranged in increasing order.
A Periodic table The Periodic Table of the Elements.
Atomic Number
The periodic table contain all chemical elements, placed in a rational order.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
atomic number
The short answer is yes - the periodic table is about order.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
the elements in the modern periodic table are arranged according to their increasing atomic number.
