Item Bank: Alkali Metals Alkaline Earth Metals Atomic Number Average Atomic Mass Element Halogen Metalloid Metals Noble Gas Nonmetal Periodic Table Transition Metals Malleable Period 1. This is the weighted average of all the isotopes of an element. 2. This is the number of protons. 3. This is a substance that cannot be broken down further by chemical means. 4. This is an element with a full valence shell, very unreactive. 5. This is a type of element that has many valence electrons, not a conductor. 6. This is a group of elements with few valence electrons that conducts heat and electricity. 7. This is the highly reactive family of elements with 7 valence electrons. 8. A horizontal row of elements in the periodic table. 9. An arrangement of elements into rows and columns according to similarities in their properties. 10. One of a class of elements having properties intermediate to metals and nonmetals. the san throughout 11. These are the highly reactive elements located in Group 1 of the periodic table. These elements have one electron in their outer energy level which makes them highly reactive with water and halogens. Average Atomic 12. These are the reactive elements located in Group 2 of the periodic table. These elements have two electrons in their outer energy level which makes them reactive with water and halogens. ed. by 13. These are the Group 3 or d-block elements. These dense metals with high boiling points can have different oxidation states and all are solid at room temperature with the exception of mercury. 14. This is a property of solid metals. Capable of being shaped or formed, by hammering or pressure. USA PREP Your Classroom Partner براز Progr Learn
