PPT-What are the properties and trends of Group 1 elements?

All pupils will be able to Baseline Describe how properties of the elements in Group 1 depend on the outer shell of electrons of the atoms Most pupils will be able to Further Explain how properties of the elements in Group 1 depend on the outer shell of electrons of the atoms. Chapter 4 and 11 (the parts we didn’t get to last test). What is the periodic table?. periodic- a regular repeating pattern. periodic table- arrangement of elements so that their physical and chemical properties follow a regular repeating pattern. History. Dmitri Mendeleev. (1834 – 1907). Russian chemist. Noticed regular (periodic) recurrence of chemical and physical properties after arranging by increasing atomic mass.. Eventually led to grouping by similar properties side by side. 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 . Classification of . elements: . The arrangement of elements in such a manner that elements with similar properties are grouped together while elements with dissimilar properties are separated. .. The classifications are as follows. law of triads. in 1817. . Each of Dobereiner's triads was a group of three elements. The appearance and reactions of the elements in a triad were similar to each other.. . At this time, scientists had . law of triads. in 1817. . Each of Dobereiner's triads was a group of three elements. The appearance and reactions of the elements in a triad were similar to each other.. . At this time, scientists had . Objectives:.
