11.  Almost 75% of all elements are classified as metals  Physical properties of metals: 1.hardness 2.luster (shininess) 3.malleability (can be pounded or rolled into shapes or flat sheets) 4.ductility (can be pulled out or drawn into wires) 5.Conductors (transmit heat and electricity easily) 6.Magnetic (attracted to magnets)  ex. iron (Fe), cobalt (Co), and nickel (Ni) 7.Most metals are solids at room temperature (high melting point)  Exception: Mercury (Hg)- -liquid at room temperature METALS CYOPT – Write in the “Metals” Section

12. GROUP 1: ALKALI METALS 1

13.  Group 1  1 valence electron  which it readily loses to become a cation  Extremely reactive – NEVER found alone in nature  Only found in compounds, combined with other elements  Reacts violently with water to produce explosions  Causes skin burns if you come into contact with it  Physical Properties:  Soft- can be cut with a plastic knife  Shiny  Lightweight  Good conductors of electricity and heat  Low melting points  Tarnishes rapidly GROUP 1: ALKALI METALS

14. BELLWORK FRIDAY: 2/24/12

15. GROUP 2: ALKALINE EARTH METALS 2

16.  Group 2  2 valence electrons  2nd most reactive group of elements in the periodic table  Chemically bond very easily by giving away 2 electrons  Physical Properties:  Fairly hard  bright white  good conductors of electricity  high melting points  high densities  Why called Alkaline? When mixed in solutions =pH greater than 7  Those pH levels are defined as 'basic' or 'alkaline' solutions GROUP 2: ALKALINE EARTH METALS

17. 3 4 5 6 7 8 9 10 11 12 GROUPS 3-12: TRANSITION METALS

18.  Groups 3-12  Largest group of elements  Most commonly found elements  Follows NO rules when finding valence electrons  Use the two outermost shells/orbitals to bond with other elements  Most elements only use the valence shell  Physical Properties:  Most are hard and shiny  All are good conductors of heat & electricity  Are fairly stable, reacting slowly or not at all with air and water  Most have very high melting and boiling points  Most dissolve in acids (except Gold!)  Most have luster GROUPS 3-12: TRANSITION METALS
