II. Section 2 metals

This overview of metals highlights their defining properties, including hardness, shininess, malleability, and ductility. It explains how metals can be shaped and stretched, as well as their conductivity for heat and electricity. A focus on alloys illustrates how metal mixtures enhance functionality. The discussion of metals in the periodic table emphasizes the similarities among families, covering alkali metals, alkaline earth metals, transition metals, and rare earth elements like lanthanides and actinides. Additionally, it acknowledges the importance of uranium in power generation.

Presentation Transcript

  1. II. Section 2 metals

  2. A. What is a Metal? • Based on the properties of hardness, shininess, malleability and ductility • Malleable- pounded into shapes • Ductile- pulled into a wire • Conductors- transmit heat and electricity easily • Magnetic- attracted to magnets • Wide range of chemical properties

  3. B. Alloys • Alloy- mixture of metals • Combine properties of other metals to be made useful

  4. C. Metals in the Periodic Table • Metals in the periodic table have similar properties within families • Alkali metals- reactive not found uncombined in nature • Only found as compounds not elements • So reactive because of valence electrons • Alkaline earth metals- not found uncombined in nature

  5. 6. Transition metals- form a bridge between reactive and non reactive metals 7. Some metals are mixed in groups 8. Lanthanides- actinides rare earth elements 9. Uranium used in power plants
