Metals, Metalloids (semi-metals), and Nonmetals



Metals, Metalloids (semi-metals), and Nonmetals Your Mission: Research 1 metal, 1 metalloid (semi-metal), and 1 nonmetal (your choice). Mark them on the periodic table below by outlining the square in colored plete the research requirements for EACH one.NOTE: Be sure to turn this handout in. It is part of your grade. (one per group)Research Requirements NOTE: Complete this list for each element you research.Name of elementCreate a square from the periodic table of the metal, metalloid, and nonmetal you are researching. Be sure to include atomic number, symbol, element name, and atomic mass. Example:1905000110490Is it a metal, metalloid, or non-metal?List three to five physical properties, and tell which of these properties indicate it is a metal, metalloid, or non-metal.Overview:How is it used?Who discovered it, or how was it discovered?Where / how do we find it? (many elements do not occur in their pure form in nature. Most are found as part of a compound.)Other facts of interestWorks Cited – (Where you got your information)Good Websites to use: Chemistry: Interactive periodic table that gives information about each element.Los Alamos National Laboratory: Interactive periodic tableChemistry 4 Kids: - Has a list of common elements with easy to read information. - Interactive periodic table that gives information about each element.Presentation:You will work by yourself. You may complete this in many different ways. The easiest and best way is just to fill out the template provided for each of your elements. However, you may also do a poster, a booklet, a pamphlet, a children’s book, or anything else you can come up with as long as each and every research requirement is present. You may do this as in an electronic format such as a PowerPoint, or Prezi.RUBRIC - This must be turned in with your project.ItemCommentsWorthEarnedFormat, spelling, punctuation, and grammar.10Periodic table square present and correct for each20All elements identified on Periodic Table and overview for each correct.20Properties of each element described and noted as prop.s of metals, non-metals, or metalloids.20Citations present and correct20Thoroughness.

It was named after the town of Ytterby, a village in Sweden.Physical Properties: Terbium is a soft, highly malleable, silvery-gray, rare-earth metal that can be cut with a knife.Density: 8.23 grams per cubic centimeterMETAL: malleable, lustrous, and very dense.Uses:Crystal stabilizer in fuel cellsActivator for green phosphors in television tubesMake laser lightToday, terbium can be obtained from the minerals xenotime (YPO4) and euxenite ((Y, Ca, Er, La, Ce, U, Th)(Nb, Ta, Ti)2O6),. It is a rare-earth metal also found in cerite, gadolinite and monazite.Other Interesting FactsConsidered mildly toxic and does not rapidly tarnish in the air.Work Chemistry, , 9/30/12.Gagnon, Steve, Thomas Jefferson National Accelerator Facility - Office of Science Education, , 9/30/1244481754635500Element Name: Discovery:Physical Properties (items marked with * indicate it is a metal, non-metal, or metalloid):Metal, Non-metal, Metalloid (circle one) Uses:Where/How do we find it?
