WebThe modern periodic table is based on the law that the properties of an element are a periodic function of their atomic number. These properties are related to the electronic configuration of the elements. We observe a common trend in properties as we move across a period from left to right or down the group. WebChemists have always looked for ways of arranging the elements to reflect the similarities between their properties. The modern periodic table lists the elements in order of increasing atomic number (the number of protons in the nucleus of an atom).
