What categories can we classify the periodic table into?
The Periodic Table is classified based on shared
characteristics.
3 main categories

What categories can we classify the periodic table into?
Metals- most are found in the middle and left side
(except hydrogen)
• Hard and shiny
Conduct heat and electricity
Malleable- can be hammered and flattened
Ductile- can be stretched into wire
Few valence electrons
•Examples: aluminum (Al), gold (Au), iron (Fe)

What categories can we classify the periodic table into?
Nonmetals -All found on the right side of periodic table
except hydrogen.
• Generally gases and brittle solids
• Dull surface
• Insulators (block heat and cold energy)
• Have more valence electrons
• Receive electrons or share when reacting with other
elements
• Examples: hydrogen (H), sulfur (S), neon (Ne)

8. Sulfur is Brittle
Gases
Copper Wire
Insulated with
plastic
Coal is dull
