I. SUBJECTIVE

The substance periodicity was demonstrated by utilizing different types of Group IA, IIA and IVA factors. Each of the samples was placed in a test tubes plus the physical express, color, and appearance was identified. The solubility of the aspect was tested through the use of normal water. The Group IIA Metal Oxides was tested with the use of the red and green litmus conventional paper. Also a well-balanced equation was written to demonstrate the reaction among oxides and water. �

II. INTRODUCTION

Chemical periodicity is defined as the similarities of chemical elements that are near each other in the periodic desk. When components are set up in order of increasing atomic amount, their physical and chemical properties recur periodically. For instance , magnesium, calcium, and strontium are all hard, very reactive, silvery metals while fluorescents, argon, and krypton are generally unreactive clear gases. This kind of periodicity comes from the valence electronic configuration settings of the components. This arrangement of elements in the purchase of increasing atomic number while using elements having similar real estate placed in top to bottom columns is recognized as periodic desk. MATERIALS/REAGENTS AND EXPERIMENTAL PROCEDURE�

For the Group IA & IIA Elements, each bit samples ofLi2CO3, Na2CO3, K2CO3, MgCO3, CaCO3 and BaCO3 was put in place the different test tubes. Following placing them inside the test tubes, we discovered the physical state, color, and appearance of every. Then we test the solubility of each and every sample by utilizing water. For the Group IVA Factor, each touch samples of C, Sn, Dans le cas ou, and Pb was put in different check tubes.
