PPT-Group I metals Trends

Group I metals Trends Melting and Boiling points Densities Reactivity Alkali Metal What is the trend in density The alkali metals generally become more dense going down the group but the trend is not perfect because potassium is less dense than sodium. Arranged the elements by increasing atomic mass, and noticed properties repeat regularly. Left a space if an element didn’t belong in a particular column. THE PERIODIC TABLE. 1H-1 (of 10). Mendeleev stated the . Introduction to the . Periodic Table. The Periodic Table. The . Periodic Table of Elements . is the chart that lists every known element according to their . physical and chemical properties. Elements are arranged in rows called . What property did Mendeleev use to arrange his periodic table?. How many periods are in the periodic table and what information can you tell by an element’s period?. Where are the groups and what information do they give you about an element?. Objectives:. AHSGE Reading 4.3 Discern organizational patterns..

Lesson Essential Question:. The Basics. The Basics. Metals, Nonmetals, Metalloids. There is a zig-zag or staircase line that divides the table.. Metals are on the left of the line, in . Classification of Elements. 1829 German Chemist J.W. . Dobereiner. published a classification system to sort elements. Noted trends and patterns related to chemical properties. Classified the elements into TRIADS(sets of three elements of similar properties. Periodic Table. B. 2p. 1. H. 1s. 1. Li. 2s. 1. Na. 3s. 1. K. 4s. 1. Rb. 5s. 1. Cs. 6s. 1. Fr. 7s. 1. Be. 2s. 2.
