1. 12/5 A/B Day
LEQ: What characteristics distinguish
metals, nonmetals, and metalloids?
1. What is the difference between ions and isotopes?
2. What is reactivity?
3. What is the difference between an element and a
compound?
4. Why can we eat salt, even though it’s made of two
poisonous elements?
5. COPY AND COMPLETE: Stable, or unreactive
elements [do/do not] form compounds.

2. Announcements:
NEXT CLASS: QUIZ on ions,
isotopes, compounds, reactivity,
and today’s lesson
(We will review beforehand!!!)

3. 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
