Representative Elements

• Chapter 5 Section 2

2
Representative Elements

• Remember that these are the elements in groups 1
  and 2 and 13 to 18
• Groups are classified by having similar
  properties

3
Group 1 Alkali Metals

• Silvery Solids with low densities and low melting
  points
• Tend to increase reactivity down the family
• Lithium (Li) is the least reactive and Francium
  (Fr) is the most reactive
• Contains Sodium (Na) and Potassium (K) too.

4
Group 2 Alkaline Earth Metals

• Denser and Harder than Alkali Metals
• Have higher melting points
• Are reactive but not as reactive as Alkali metals
  
• Contains Beryllium (Be), Magnesium (Mg), Calcium
  (Ca), Barium (Ba), Radium (Ra)

5
Group 13 Boron Family

• Are all metals except Boron
• Boron is a brittle, black metalloid
• Used to make a variety of products
• Such as Pots and Pans, Aluminum Cans, and
  Baseball Bats

6
Group 14 Carbon Family

• A mixture of non-metals, metalloids and metals
• Contains Carbon a non-metal
• Contains Silicon
