Notes 1-3

Question 1

Chemistry

Answer 1

The study of the composition, structure, and properties of matter and the changes it undergoes.

Question 2

6 Types of Chemistry

Answer 2

organic, inorganic, physical, analytical, biological, theoretical

Question 3

Groups

Answer 3

Vertical (up and down) columns of the periodic table. Each group contains similar chemical properties

Question 4

Periods

Answer 4

Horizontal (side to side) rows of elements in the periodic table. Physical and chemical properties change somewhat regularly across the period.

Question 5

Lanthanide and actinide series

Answer 5

The two sets of elements placed below the periodic table.

Question 6

Malleable

Answer 6

A substance’s ability to be hammered into sheets

Question 7

Ductile

Answer 7

Can be made into fine wire

Question 8

Tensile Strength

Answer 8

Ability to resist breaking while pulled

Question 9

Metals

Answer 9

-Conduct heat and electricity
-Solid
-Malleable
-Ductile
-Tensile
-Shiny (grey or white luster)

Question 10

Non-metals

Answer 10

-Poor conductors of heat and electricity
-Gas (mostly)
-Ex. nitrogen, oxygen, fluorine, chlorine
-Brittle (easy to break)

Question 11

Metalloids

Answer 11

-Stairstep on the periodic table
-Elements that have some characteristics of both metals and nonmetals
-Solid at room temperature
-less malleable than metals but not as brittle as nonmetals
-semiconductors of electricity

Question 12

Noble gasses

Answer 12

-Group 18
-Un-reactive
-Low reactivity sets them apart from other families of elements
