1c Students know how to use the periodic table to identify alkali metals alkaline earth metals and transition metals trends in ionization energy electronegativity and the relative sizes of ions and atoms. 1. . What . are the trends for ionization energy? Why do these trends exist?. 2. . As you go across a period, do elements get better or worse at attracting electrons? . Justify. . your response.. 3. Trends and Similarities. Trends of the Periodic Table:. At the conclusion of our time together, you should be able to:. . Give a trend across and down the Periodic Table for metallic characteristics, reactivity, atomic radius and ion radius, . Periodic Trends. When the elements are arranged on the Periodic Table, certain characteristics of atoms show . trends. within the groups and periods.. These trends are observed as a . gradual increase. Conceptual Reminders: Waves/Blackbody Radiation Energy. Example. A lamp rated at 40.0 J/sec emits violet light of wavelength 422 nm. What is the energy of the photons? How many photons of violet light can the lamp generate in 2.0 sec?. Expectations: B2.2, B3.3 . 1.7 Periodic Trends and Atomic Properties. Learning Goals. By the end of this class I will…. Describe and explain periodic trends related to:. Atomic radii. Ionic radii. Electron Configuration and Periodic Properties. Electron Configuration and Periodic Properties. Objectives: . Define atomic radius and ionization energy.. Compare the periodic trends of atomic radii and ionization energy.. What is the difference between a Bohr models, Lewis Dot Diagram, and the Nuclear Symbol? . 1. Periodicity . Periodic Trends . 2. Periodic Law . The chemical and physical properties of the elements are periodic functions of their atomic numbers; properties of the elements occurred at repeated intervals called periods.. Ga. . Standards.

Definition: Half . of the distance between . Turn to page 3 in the Unit Note Packet . History of the Periodic Table. In the . mid-1800’s. , . Dimitri Mendeleev published a table of all of the known elements, 70 elements to be exact. . Not until . Periodic table. Elements are arranged based on similarities in their properties. Dmitri Mendeleev is credited with our current periodic table. Even predicted the existence of elements that were not yet discovered(i.e. Gallium). What patterns exist on the periodic table?. 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 .
