1. Periodic Table Trends
Physical Science
2016

2. B=Metals, P=Metalloids, Y=Nonmetal

3. Metals Elements that are: Shiny Opaque
Good conductors of electricity and heat
Malleable

4. Nonmetals Elements that are: Poor conductors of electricity and heat
May be transparent
Brittle
Can be solid, liquid, or gas

5. Metalloids
Has characteristics similar to both metals and nonmetals

6. Trends Periodic trend = a gradual change in elemental properties
Periodicity = a trend that repeats

7. Example of a Trend Atomic size decreases from left to right K Ca Sc Ti
Potassium
Scandium
Calcium
Titanium

9. Alkali Metals Makes an alkaline solution when mixed with water
Known to be used to make soaps
Ex: Sodium

10. Alkali Earth Metals Makes an alkaline solution when mixed with water
Elements are fire resistant
Ex: Beryllium

11. Transition Metals Harder than alkali metals Less reactive with water
Ex: Zinc
Ex: Iron

12. Inner Transition Metals
Lanthanides
Difficult to purify
Used in LED’s
Actinides
Mostly made in a laboratory
Ex: Uranium

13. Boron Group
Due to its ionic bonding, these elements have highly desirable metallic traits.

14. Carbon Group Occur in nature as both combined and elemental versions.
Not very reactive.

15. Nitrogen Group
Has some characteristics of semi-metals

16. Chalcogens (Oxygen) “ore-forming” in Greek Commonly found in ores Ex:
Sulfur ore

17. Halogens “salt-forming” in Greek Known to form salts
Found in halogen lamps
Ex: Bromine

18. Noble Gases All unreactive gases
Doesn’t like to combine with other elements
Ex: Helium
