1. Periodic Table
Families and Patterns

2. Groups Determined by electron configurations
Outer configuration is the same for every element in a column (group/family)
Classified into 4 MAJOR Groups
Representative Elements
Transition Elements
Inner Transition Elements
Noble Gases

3. Representative Elements
Characterized by outermost s and p sublevels containing electrons
Subgroups
Alkali Metals
Alkaline Earth Metals
Boron Group
Carbon Group
Nitrogen Group
Oxygen Group
Halogens

4. Transition Elements
Characterized by outermost s and “nearby” d sublevels containing electrons
Also referred to as Group B elements

5. Inner Transition Metals
Characterized by outermost s and “nearby” f sublevels containing electrons
Most are synthetic and many are radioactive
Also referred to by row
Lanthanide Series (Row 6)
Actinide Series (Row 7)

6. Noble Gases Characterized by outermost s and p sublevels being FILLED
Non-reactive elements
Rarely combine with other elements to form compounds

7. Oh, to be king for a day…
All elements want to be like a noble gas (filled outermost s and p sublevels)
Elements lose or gain electrons in order to be like the noble gases.
Representative elements will gain or lose up to four electrons
Transition and Inner Transitions elements will lose any number of electrons and the number of electrons lost can vary.

8. Lost or Gained Group 1 will lose 1 electron
Group 2 will lose 2 electrons
Group 13 will generally lose 3 electrons
(some exceptions)
Group 14 may gain or lose 4 electrons
(depends on who its combining with)
Group 15 will gain 3 electrons
Group 16 will gain 2 electrons
Group 17 will gain 1 electron
