5. Parts of the Periodic Table Metals - elements possessing similar properties such as metallic luster, reacting well with elements other than metals, and easily conducts electricity. Examples: Copper, Potassium, Sodium Nonmetals – elements possessing the opposite characteristics of metals. They are often found in the gaseous state. Examples: Hydrogen, Oxygen, Nitrogen Metalloids found between metals and nonmetals; often have properties of both. Ex: Silicon, Boron

19. Atomic Radius pattern Where would you find the element with the a) largest radius b) smallest radius? a) Bottom, left-hand side b) Top, right-hand side

21. Ionization Energy pattern Where would you find the element with the a) largest ionization energy b) smallest ionization energy? a), Top, right-hand side b) bottom left-hand side

23. Shielding Effect pattern As you move down the periodic table there are more electrons inside an element. This creates less of an attraction to the valence electrons. (the electrons in the lower energy levels are taking up too much of the nucleus’ attention.)

25. Electronegativity pattern F is the most electronegative element at 4.0 and Francium is the least at 0.7.
