PPT-Electron Configuration for Elements

Electron Shells Periods on the periodic table are similar because they have the same number of electron shells Within these shells there are layers called sublevels a shell can have between 1 and 4 sublevels. Configuration . for Elements Above Atomic # 18. Electron Shells. Periods on the periodic table are similar because they have the same number of electron shells.. Within these shells there are layers called sublevels', a shell can have between 1 and 4 sublevels.. Energies in Relation to Periodic Table. 3d. 4f. 1s. 2p. http://www.docstoc.com. Energies of Orbitals. E. Hydrogen. ei. Everything other than Hydrogen. Questions: . What . is the difference between the two? Why do you think hydrogen is different?. Electron Configurations. The way electrons are arranged in atoms. Energy Levels (Principle Quantum Number – n). First energy level. Only s sublevel (1 s orbital). Only 2 electrons. 1s. 2. Second energy level. Unit 13. Electrons and their Relationship to the Periodic Table. Basic Periodic Table Nomenclature. Identify Valence Electrons from the . Periodic Table. Identify Named Groupings of Elements on the Periodic Table. Elements in Group 1 are called . alkali metals. . lithium, sodium, potassium, rubidium, cesium, and francium . • Alkali metals are so named because they are metals that react with water to make alkaline solutions. . Tutor: Peter Harris. Click on the buttons to move between slides. .. (Make sure you are in “Slide Show” mode). The aims of this course are:. ● . to explain how X-rays are generated in the electron microscope. DO NOW. Pick . up your paperwork. Pick up two handouts. Get out Electron Configuration Notes, your Blank Periodic Table, and your green periodic table.. RULES. Aufbau. Principle. Each electron occupies the lowest energy orbital available. Electrons are added from the ground state up. Electrons fill in increasing energy order.. Lesson Objectives. Understand the relationship between the number of orbitals in various energy sublevels and the length of the periods in the periodic table.. Identify each block of the periodic table and be able to determine which block each element belongs to based on its electron configuration.. Electron Configurations, Valence Electrons, and the Periodic Table. The periodic table is arranged by grouping elements with similar chemical properties- connection between electron configuration and chemical properties.

The only electron source designed for highresolution imaging and suitable for various kinds of materials The aims of this course are:. ● . to introduce the principles of scanning electron microscopy. ● . to describe the components of the microscope and explain how they work. ● . to highlight some of the problems which can arise during imaging. A simplified approximation of the principle of WDS analysis is as follows:. C. A. (sp) = [I. A. (sp)/I. A. (st)]C. A. (st). Where . C. A. (sp) = concentration in specimen. C. A.
