By the twentieth century, it became apparent that the periodic relationship involved atomic numbers rather than atomic masses. The modern statement of this relationship, the periodic law, is as follows: the properties of the elements are periodic functions of their atomic numbers.A modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with Download the Selina Concise Chemistry Solution for Class 10 Chapter 1 Periodic Table, Periodic Properties and Variations of Properties.

Lithium, sodium and potassium are in the same group, alkali metals or Group 1A, because the Periodic Table is arranged according to the Periodic Law which states that chemical •The groups in the Periodic Table are numbered from 1 to 18. •Elements in the same group have the same number of valence electrons. •Example: Sodium and potassium are both found in group 1 which means that they both have 1 valence electron KMP/ChemUnit/SK017-10/11 4 4 Group number = number of valence electron (if the element is in block s and d) OR The Periodic Table • Periodic Law - When the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties • Modern Periodic consists of: Periods - Horizontal rows of the periodic table (side to side) Groups or families - – vertical (up and down) In studying the periodic table, you might have noticed something about the atomic masses of some of the elements. Element 43 (technetium), element 61 (promethium), and most of the elements with atomic number 84 (polonium) and higher have their atomic mass given in square brackets.
