Today’s LEQ: What characteristics distinguish metals, nonmetals, and metalloids?

By the end of today, you should be able to…

1. Identify materials that are malleable, ductile, conductors, and insulators.

2. Observe a specific material to determine whether it is classified as a metal, a nonmetal, or a metalloid

3. Predict properties of elements by looking at the periodic table
