  1. The Periodic Table

  2. The Periodic Table

  3. The Table in General • Columns • Called groups • Elements in a group have similar chemical and physical properties • As you go from top to bottom elements get larger • Atoms get larger in size • All of the elements in each group have the same number of valence electrons.

  4. Smallest Element #1 Largest Element #114

  5. The Table in General • Rows: (Periods) • First elements very reactive solids • Last element non reactive gas • Get less reactive as you move from left to right • Reactive-bonding with other elements • Elements become less metallic left to right • The period tells you the number of orbitals.

  6. The Table in General • Families: • Cluster of elements on the periodic table • Determined by their chemical properties

  7. Rows: (Periods) More Reactive More Metallic Less Reactive Less Metallic

  8. Color all these elements one color and add it to your key One electron in the valence shell (outermost energy level) Soft, less dense metals Most reactive of all metals React violently with water to form bases Never found free (alone) in nature Found in soap, salt, baking soda 1.

  32. Three Categories • Metals • Non-Metals • Metalloids

  33. Properties of a Metal • Physical • superior electric and thermal conductivity • high luster • High density • Malleable- ability to be deformed under stress without cleaving (breaking) • Alkali & Alkaline Earth metals are extremely reactive, low density, hardness, and melting points

  34. Properties of a Metal • Chemical • Form positively charged ions • Metals can be easily oxidized. Oxidation is informally known as the process of corrosion • Metals can react with acid • Some metals, like sodium or calcium will react with water to make a base

  35. Metalloids: Draw the step ladder & identify the metalloids (use spots) • Draw in the step ladder and mark the Metalloids.

  36. Definition of a Metalloid • Found in the area between the metals and the nonmetals on the Periodic Table • Sometimes called semi-metals and have characteristics that are similar to both metals and nonmetals.

  37. Non-Metal: Identify the non-metals (use stripes) • Mark the Non-Metals

  38. Properties of a Non-Metal • Physical • low electrical conductivity • brittle when solid • Most are solid and gas (Bromine is a liquid) • dull • Do not conduct heat end electricity well • lower melting points and boiling points than metals • Chemical • Form negatively charged ions
