In the modern periodic table the elements are arranged according to their atomic number not their relative atomic mass. The periodic table is a tabular array of the chemical elements organized by atomic number from the element with the lowest atomic number hydrogen to the element with the highest atomic number oganesson. By atomic mass B.
The atomic number is the number of protons in an atom of that element. In the modern periodic table the elements are arranged according to their atomic number not their relative atomic mass. The elements are arranged so that elements in a group all have the same valence subshell and thus have similar properties.
Where are the most reactive metals located on the periodic table. The column at the far left side of the table. The atomic number of an element is the number of protons in the nucleus of an atom of that element.
The periodic table provided the template for classification of elements by their chemical properties and atomic weight. Mendeleev created his chart between the years of 1868 and 1870 as he was writing his book titled The Principles of Chemistry.
