How is the modern periodic table arranged? What are the periodic properties of the elements? What do elements in the first two columns of the periodic table have in common? What is the first element on the periodic table? What elements on the periodic table are nonmeta...
The periodic table is a tabular arrangement of the chemical elements by increasingatomic number, which displays the elements so that one may see trends in their properties. The Russian scientistDmitri Mendeleevis most often credited with inventing the periodic table in 1869. The modern table is der...
The periodic table of the elements is a representation of all known elements in an orderly array. The periodic law presented by Dmitri Mendeleev in 1869 stated that if the (known) elements are arranged by atomic weight, then certain trends in chemical properties can be observed. That is to s...
