1. Metals Non-Metals

2. Properties of Metals Shiny Conduct heat & electricity
Malleable (bendable)
Ductile (can be bent into wires)
Mostly solids(exception: Mercury)
Located in Groups 1-12
Family names include: Alkali Metals, Alakaline Earth Metals& Transition Metals

3. Properties of Non-Metals
Can be solids (brittle) and liquids, but are mostly Gases
Do not conduct heat & electricity
Located in Groups 13-18
Family names include: Halogens & Noble Gases

4. Where are the nonmetals located on the periodic table?

5. Where are the metals located on the periodic table?

6. Horizontal rows are called PERIODS
Periodic table
Mendeleev
The periodic table arranges all the elements in groups according to their properties.
Vertical columns are called GROUPS
Horizontal rows are called PERIODS 6

7. History of the Periodic Table
Dimitri Mendeleev – 1869
“Father of the Periodic Table”
Arranged the elements based on
Density
Chemical properties
Atomic mass
Henry Moseley -
Atomic number
CURRENTLY ARRANGED IN THIS MANNER

8. React explosively with water
Alkali Metals - Group 1:
1 valence electron
React explosively with water
Cesium
Shiny, Silver and Soft
Not found in Nature

9. Alkaline Earth metals – Group 2: 2 Valence electrons
Not as soft as Alkali metals
Barium
Silver in Color & react mildly in water, conductive

10. Have high Conductivity
Transition Metals – Groups
Transition Metals
Mercury - liquid
Have high Reactivity
Have high Conductivity

11. Inner Transition Metals
Some Radioactive
