PART I ATOMIC RADUIS TREND GOING ACROSS THE PERIODIC TABLE PART II ATOMIC RADUIS TREND GOING DOWN A GROUP 1. Refer to the graph that you created in Part I of this assignment. Describe the general trend or patterns that you observed in the atomic radius as you go across the periodic table. (2 points) It looks like the atomic radius is bigger if the atomic number is small. This may be because of the decrease of the pull that the protons give the electrons the smaller the atomic number.2. In Part

Causes and Effects of Consumer Culture In the mid-nineteenth century‚ the global business market had been improved by the introduction of mass production and management for the industries. With the increase of income and level of education‚ the consumers had higher purchasing power to fulfill their needs as well as their desire (Miller 1981‚ quoted in Featherstone 1991‚ 172). The consumer culture was later brought by the various advertising paths in 1920s (Featherstone 1991‚ 172). Consumer culture

PERIODIC CLASSIFICATION OF ELEMENTS Introduction There are 115 elements that are known at present. Some elements have similar properties whereas some others have completely contrasting properties Scientists began to look for some pattern in the properties of these elements Dobereiner’s triads In 1817‚ Johann Wolfgang Dobereiner‚ a German chemist‚ classified elements into groups based on their properties. He kept all elements having similar properties in one group. Most of his groups had three

come across a laboratory‚ classroom‚ chemistry textbook or lecture theatre that doesn’t contain a periodic table of the elements. It required the immense research and determination of the scientist Dmitri Mendeleev to show us that all elements followed a natural form and provided us with the first decent periodic table. There are 111 elements recognised today by IUPAC and they are arranged in the periodic table in horizontal groups and vertical periods. The eight groups consist of the alkali metals

the properties of the elements recur in the same pattern. With the works of these scientists‚ the periodic table was created as well as the periodic law. With this set‚ scientists as of today had been able to organize the elements without much trouble and were able to discover unknown elements. Although there are many elements in the world and many of them have not always been known of‚ the periodic table had been created to classify these elements as well as the table’s corresponding patterns and

Introduction: The periodic is a table of the elements‚ organized in order of increasing atomic number. Elements that have similar chemical properties and electronic structures appear in vertical columns‚ or also called groups. The Periodic Law states that when elements are placed in order of increasing atomic number‚ their physical and chemical properties display a periodic pattern. The purpose of the lab was to discover how two periodic properties‚ atomic radius‚ and first ionization energy‚ vary
