  1. The Elements 1.3

  2. The Periodic Table • Groups – vertical columns on the p.t. #1-18 • AKA Families • Similar Properties • Periods – horizontal rows on the p.t. • Consecutive numbers of p+, e-, n0

  3. Periodic Table

  4. Types of Elements • Metals – an element that is a good conductor of electricity and heat • Shiny, malleable, ductile, solids, high tensile strength • There are some exceptions mercury

  5. Periodic Table • Two rows below the periodic table are the lanthanide and actinide series • These rows fit after #57 and #89 • They are only at the bottom to keep the width of the chart smaller

  6. Types of Elements • Non-Metals – element that is a poor conductor of heat and electricity • Mostly gases at r.t. • The ones that are solids are brittle

  7. Types of Elements • Metalloids – element that has some characteristics of metals and some of non-metals • Stair step line • Solids at r.t. • Less malleable than metals, but not as brittle as non’s • Semi conductors of electricity

  8. Types of Elements • Noble Gases – group 18 on the p.t. • Unreactive • Gases at r.t.
