Metals, Nonmetals, and Metalloids (Vocabulary)

Discover the fundamental properties of metals, nonmetals, and metalloids in this overview. Learn about luster, malleability, conductivity, ductility, magnetism, and sonority as key characteristics that distinguish these elements. Metals exhibit shiny luster, high malleability, and excellent conductivity, while nonmetals are typically dull, brittle, and act as insulators. Metalloids bridge the gap between these two categories with mixed properties. Expand your knowledge with essential formulas for calculating density and volume, including methods like water displacement.

Presentation Transcript

  1. Metals, Nonmetals, and Metalloids (Vocabulary)

  2. Luster • The way an objectreflects light; • Examples • Shiney • Dull • Metalic • Waxy

  3. Malleability • How well an objectcan be hammered into thin sheets. • Examples • Flattened penny • Aluminum can • Tin foil • Aluminum foil

  4. Conductivity • How well an objectallows electricity to move through.

  5. Ductility • Can be stretched into wire.

  6. Magnetism • Attracted to or repelled by a magnet.

  7. Sonorous • Produces a sound when struck with another object.

  8. Metals • Elements which have physical properties such as good conductivity, shiny luster, malleability and ductility.

  9. Nonmetals • Elements which have physical properties such as no conductivity (an insulator), dull luster, and brittleness (will break).

  10. Metalloids • Elements which can have both properties of metals and nonmetals. • Also may be called a semi-conductor.

  11. Density Formula • Density = mass/volume • D=m/v • (I density)

  12. Volume Formula • V = L x W x H • Volume=length x width x height

  13. Water Displacement • A method used to calculate the volume of an irregular shaped object.
