The modern periodic table is a tabular representation of all the chemical elements in the order of their atomic number, their electron configuration and the rows in the table are called periods. A printable periodic table is an essential tool for students and chemists. In first period only two elements are present. The number of valence electrons in atoms is the basis of the regular patterns observed by mendeleev in 1869, patterns which ultimately have given us our modern periodic table. Here, you will find that the elements present in any one group have the same number of valence electrons. To learn an element's name, atomic number, electron configuration, atomic weight, and. The modern periodic table or the long form of periodic table is a periodic table (given by bohr) in which the arrangement of the elements has been made on the basis of the atomic number of the elements, which is a more fundamental property of the elements. This table is a work in progress. So, mendeleev periodic table was modified and it is called now modern periodic table which states that the physical and chemical properties of there are altogether 7 periods in the periodic table 2) vertical columns are called groups. In the modern periodic table, the group number 3 of period six contains the lanthanum series which are the rare earth elements. You can place it where you need it while solving problems, mark it up, and print a new one whenever you. The modern periodic table solved another problem by placing the rare earth elements such as cerium, lanthanum, erbium etc in a separate table at the bottom of the periodic table, so as not to interfere with the periodic law. Today, the periodic table organizes the elements in horizontal rows, or periods, by order of increasing atomic number, which equals the number of protons in the atomic nucleus of each element.
