Wake Up! Sing along (if you’d like!) Song: Day 1 on the periodic table Song: Day 2 with pictures Song: Day 3 with the words

Where are they located on the Periodic Table of Elements? Look in your book (p. 338-339) for the zigzag line!

What are the properties of metals, nonmetals, and metalloids?

Use a Venn diagram to compare their properties metals nonmetals metalloids Try it: Sort your cards into the correct circle. Use your book (pages 340-341) to help you.

metals ---- nonmetals Solids at room temp. (except mercury) Most are gases

metals ----- nonmetals higher melting points lower melting points

metals ---- nonmetals malleable harder brittle (break easily) (can be pounded & shaped) harder brittle (break easily) Softer than metals

metals ---- nonmetals Ductile (can be drawn into wire) Not ductile

metals ---- nonmetals lustrous (shiny) dull

metals ---- nonmetals Good conductors of heat and electricity Poor conductors (good insulators)

metals ---- nonmetals Includes the least reactive group (18) (noble gases) *most stable Includes the most reactive group (1) (alkali metals) Brainiac Video (no commercials) Backup copy on teachertube--with commercials

Metalloids Have some of the properties of metals and some of the properties of nonmetals Include semiconductors (Used in electronics)

metals ---- nonmetals Tend to lose electrons (form positive ions +) Tend to gain electrons (form negative ions -)
