The modern Periodic Table arranges elements based on properties. These properties include valence electrons of the elements and density for example.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
Both arrange elements in groups of elements having similar properties.
Both arrange elements in groups of elements having similar properties.
In Mendeleev's periodic table the elements are arranged in increasing atomic mass and repeating properties whereas in in the modern periodic table the elements are arranged in increasing atomic number and repeating properties.
Henry Moseley founded modern periodic table. He proved that atomic number is the fundamental property to arrange the elements.
The inversion is due to the isotopic composition of these elements.
The elements are arranged in what is called the periodic table.
The Periodic Table of Elements.
In the modern version of the periodic table, the elements are arranged in increasing order of the atomic number. The chemical properties of an element can be predicted by its group. For example group 1 elements react violently to give away one electron to form +1 ions where group 18 elements are inert in standard temperature and pressure. This periodic table was introduced by Henry Mosley.
