4. What is the significance of periodic table?

3. What is the periodic table?
A system used to organize elements by
properties
atomic structure

5. WHAT ARE THE MAIN CATEGORIES OF ELEMENTS?

6. PROPERTIES OF METAL Most are shiny solids except for Mercury.
Ductile- can be shaped into wires.
Malleable- can be hammered into sheets.
Good conductor of heat and electricity.
Melting point: 962 °C
Density: 10.5g/mL
Ex: Silver (Ag), Gold (Au), Iron (Fe) and Tin (Sn)

7. PROPERTIES OF NONMETAL
Dull, yellow material
Brittle-breaks easily
Shatters when hammered
Poor conductor of heat and electricity.
Good insulator (keeps temperature low or high)
Melting point: 113 °C
Density: 2.1 g/mL
Ex: Hydrogen (H), Carbon (C),
Nitrogen (N) and Oxygen (O)

8. PROPERTIES OF METALLOID
Shiny, blue-gray material
Brittle-breaks easy
Shatters when hammered
Better conductor of heat and electricity than nonmetal.
Melting point: 630 °C
Density: 6.7 g/mL
Ex: Aluminum (Al), Silicon (Si), Arsenic (As), Boron (B)

9. Color your own periodic Table

11. What is atomic structure?
The amount of protons, neutrons, and electrons that an element has.

12. Atomic Number= number of protons
The periodic table increases in atomic number
Atomic Number

13. The alpha letters used to denote the element
Atomic Symbol
The alpha letters used to denote the element
Atomic Symbol

14. How much the element weighs *Protons + Neutrons= Atomic Mass
Average of all natural isotopes
Atomic Mass

15. elements with different number of neutrons stable and unstable
Isotopes
elements with different number of neutrons
stable and unstable

16. Label your element on the side of your notes or notes illustrated1. 2. 3.

17. Practice reading the Periodic Table
With your partner figure out:
how many protons, neutrons, and electrons there are for each element.

18. Horizontal rows are called periods Properties gradually change
The periodic Table
Horizontal rows are called periods
Properties gradually change
Atomic number increases
Vertical columns are called groups
Each group has similar properties
**label on your periodic table of elements

19. Notes illustrated write summary bottom of pg 53

20. Practice reading the periodic table
worksheets, rounding

21. Periodic Table Reading
Go to Jupiter and
