2. Warm up 1/4/2017
Create a divider Unit #7 Atomic Structure
Assignment #1
Define/ write what you know about a periodic table. 
Journal checks will be done every time you are testing (about every 2 weeks).

3. Share your answer with your shoulder partner

9. PERIODIC Table
Elements are arranged in order of increasing atomic number.
Vertical columns: Groups, share similar physical and chemical properties. Also share valence electrons quantity.
Horizontal rows: Periods: They are in the same shell.
Metals, Non-Metals, and Metalloids are in different regions.

10. CONDUCTOR
A material or an object that transfers heat, electricity, light, or sound. 

11. INSULATOR
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it.

12. MALLEABILITY
Malleability is the quality of something that can be shaped into something else without breaking.

13. DUCTILITY
Ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire.

14. BRITTLE
Having hardness and rigidity but little tensile strength; breaking readily with a comparatively smooth fracture, as glass.

15. LUSTER
The shine from the surface of a mineral. Luster is important in describing different kinds of minerals. It is usually characterized as metallic, glassy, pearly.

16. DULLNESS
Having very little depth of color; lacking in  richness or intensity ofcolor.

17. DENSITY
 Put simply, if mass is a measure of how much 'stuff' there is in an object, density is a measure of how tightly that 'stuff' is packed together.
(density = mass/volume). 

18. MELTING POINT
The temperature at which a given material changes from a solid to a liquid, or melts.

19. STATE OF MATTER
One of the four principal conditions in which matter exists—solid, liquid, gas, and plasma
A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. 

20. Metals Shiny High Density Melt at High Temperatures
Good Conductors (heat/electricity)

21. Non-metals Dull Low Density Melt at Low Temperatures
Bad Conductors (heat/electricity)

22. metalloids Shiny or Dull
Better Conductors than Nonmetals but worse than Metals (semiconductors).
In between metals and non-metals.
Solids (at room temperature).

23. sulfur Yellow Dull Brittle Non-metal Very Bad Conductor etc
