First person to classify elements in a universal manner
Arranged so that elements in the same column
have similar properties and increase in atomic
mass

Modern Periodic Table
Periodic law – when elements are arranged in
order of increasing atomic number (protons), their
physical and chemical properties show a periodic
pattern
Groups
• Columns are called groups
– Elements in the same group have similar properties
caused by the number of valence electrons
Families (Groups With Names) Valence Electrons
Group 1 – Alkali Metals 1
Group 2 – Alkaline Earth Metals 2
Groups 3-12 – Transition Metals
Group 17 - Halogens 7
Group 18 – Noble Gases 8
Periods
• Rows are called periods
– Tell how many principle energy levels have
electrons in them
– Also where valence electrons are located
Metals
Found to the Left of the Staircase (Majority of elements)
Physical Properties Chemical Properties
1) Luster (shiny) 1) Easily lose electrons
2) Good conductors of (forming + ions)
heat and electricity
3) Ductile (drawn in wires)
4) Malleable (hammered
into sheets)
Nonmetals
Found to the right of the staircase + hydrogen
Physical Properties Chemical Properties
1) Dull 1) tend to gain electrons
2) Poor conductors (form – ions)
3) Brittle
Metalloids (Semimetals)
6 Staircase elements – B, Si, Ge, As, Sb, Te
Properties – a mix of metals and nonmetals
1) Solids
2) Shiny or dull
3) Ductile
4) Malleable
5) Conduct better than nonmetals, but not as
well as metals
Lanthanides & Actinides
• F block of periodic table
States at STP
Solid - Majority of elements are solids; all metals
and metalloids are solid except mercury (liquid)
Liquid – Two elements are liquids; Bromine
and Mercury
Gas – noble gases, nitrogen, oxygen,
fluorine, chlorine, and hydrogen are gases
