Metals

Metals. Capable of reflecting light (luster). Good conductors of heat and electricity. [http://www.bsieducation.org/Education/14-19/topic-areas/applied-science/images/043.jpg]. Metals. Pure metals are held together by metallic bonding. Electrons can travel “between” the atoms.

Presentation Transcript

  1. Metals • Capable of reflecting light (luster). • Good conductors of heat and electricity. [http://www.bsieducation.org/Education/14-19/topic-areas/applied-science/images/043.jpg]

  2. Metals • Pure metals are held together by metallic bonding. • Electrons can travel “between” the atoms. [http://www.bbc.co.uk/scotland/education/bitesize/higher/img/chemistry/energy/bsp/fig01.gif]

  3. Metals • All are solids at room temperature (except mercury!) [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG10_17-03UN.JPG]

  5. Metals • Malleable – can be hammered or rolled into sheets. • Ductile – can be made into wires.

  6. Alkali Metals • Found in group 1 or 1A [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter06/Text_Images/FG06_08-03UN.JPG]

  7. Alkali Metals • All have 1 Valence Electron • Only exist as pure elements under controlled conditions!!! • Most reactive metals on table.

  8. Alkali Metals • Are very “soft” and have low density and melting points • Usually form compounds with group 17. [http://www.microchem.de/elec000a-k.JPG] Click here for sodium + chlorine reactivity video

  9. Alkaline Earth Metals • Found in group 2 or 2A [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter06/Text_Images/FG06_08-12UN.JPG]

  10. Alkaline Earth Metals • All have 2 valence electrons. • Can exist as pure elements, because they are less reactive than alkali metals. [http://wps.prenhall.com/wps/media/objects/476/488316/Instructor_Resources/Chapter_09/FG09_34.JPG]

  11. Alkaline Earth Metals • Produce bright colors in flame tests. Click here for a Magnesium video clip.

  12. Alkaline Earth Metals • This group contains the most abundant metal in our bodies…. • Calcium [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter01/Text_Images/FG01_02-04UN.JPG]

  13. Transition Metals • Found in groups 3-12 or the “B” groups of the table [http://library.thinkquest.org/3659/pertable/trametal.gif]

  14. Transition Metals • Occur commonly in nature as pure elements. • Form colorful compounds. [http://wps.prenhall.com/wps/media/objects/602/616516/Media_Assets/Chapter20/Text_Images/FG20_11.JPG]

  15. [http://cwx.prenhall.com/bookbind/pubbooks/hillchem3/medialib/media_portfolio/text_images/CH22/FG22_21.JPG][http://cwx.prenhall.com/bookbind/pubbooks/hillchem3/medialib/media_portfolio/text_images/CH22/FG22_21.JPG]

  16. [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG24_09_02UN.JPG][http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG24_09_02UN.JPG]

  17. Transition Metals • Many transition metals are made into alloys in order to combine their properties. • Metals are melted then mixed together. [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG24_09_02UN.JPG]

  18. The purity of gold is determined by the different ratios of gold, copper, and silver present. [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG24_09_02UN.JPG]

  19. Steel is an alloy of carbon & iron. [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG24_09_02UN.JPG]

  20. Inner Transition Metals • Found at the bottom of the table and belong in periods 6 and 7. [http://library.thinkquest.org/3659/pertable/intmetal.gif]

  21. Inner Transition Metals • Very rare elements. • Most are radioactive and/or manmade elements. (Especially after Uranium!)
