Chemistry Chapter 2 Notes 5: The Periodic Table

Front 1

What does the periodic table do (what is it's function?)

Back 1

The periodic table organizes all the known elements and gives a good deal of information about each one.

Front 2

Name the 4 physical properties of metals

Back 2

1) good conduction of heat and electricity
2) malleability (can be hammered into thin sheets)
3) ductility (can be pulled into wires)
4) (often) lustrous appearance

Front 3

Metals tend to (gain/lose) electrons to form positive ions.

Back 3

lose

Front 4

Nonmetals

Back 4

elements that appear in the upper right hand corner of the periodic table. chemically, they tend to gain electrons to form negative ions, but can also share electrons to form covalent bonds.

Front 5

Metalloids (or Semimetals)

Back 5

elements bordering the "staircase"- have properties between true metals and true nonmetals
(Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Astatine)

Front 6

Group or Family (of the Periodic Table)

Back 6

vertical columns of elements in the periodic table

Front 7

Name for the elements in group 1A of the periodic table

Back 7

Alkali Metals

Front 8

Name for the elements in group 2A of the periodic table

Back 8

Alkaline Earth Metals

Front 9

Name for the elements in group 6A (or 16) of the periodic table

Back 9

Chalcogens

Front 10

Name for the elements in group 7A (or 17) of the periodic table

Back 10

Halogens

Front 11

Name for the elements in group 8A (18) of the periodic table

Back 11

Noble Gases

Front 12

Representative Elements

Back 12

Elements in longer columns (the A groups: 1, 2, 13-18)

Front 13

Transition Elements

Back 13

Elements in the "B groups"

Front 14

Inner Transition Elements

Back 14

The elements in the rows below the main body of the periodic table- each row is named after the elements it follows in the main body of the table: Lanthanide and Actinide

Front 15

Periods

Back 15

the horizontal rows of the periodic table- these are simply numbered as you go down (period 1 contains Helium and Hydrogen)
