METALS PHYSICAL PROPERTIES HARDNESS SHININESS MALLEABILITY- TO BE ABLE TO BE HAMMERED INTO SHAPES DUCTILITY- CAN BE PULLED OR DRAWN INTO A LONG WIRE CONDUCTORS- TRANSMIT HEAT AND ELECTRICITY MOST SOLID AT ROOM TEMPERATURE EXCEPT Hg

METALS CHEMICAL PROPERTIES REACTIVITY- THE SPEED AND EASE WITH WHICH AN ELEMENT COMBINES OR REACTS WITH OTHER ELEMENTS CORROSION- THE REACTION WITH OXYGEN CAUSING RUSTING MOST REACTIVE ARE CLOSER TO THE LEFT SIDE OF THE PERIODIC TABLE AND TOWARD THE BOTTOM

ALLOYS MIXTURE OF METALS COMBINE TO USE THE BEST PROPERTIES OF BOTH BRONZE= COPPER AND TIN BRASS= COPPER AND ZINC STAINLESS STEEL= CARBON AND CHROMIUM AND VANADIUM

ALKALI METALS GROUP 1 VERY REACTIVE NEVER FOUND FREE IN NATURE ONLY FOUND IN COMPOUNDS VERY SOFT AND SHINY CAN CUT WITH PLASTIC KNIFE ONE VALENCE ELECTRON SO TRANSFER EASILY TO OTHER ELEMENTS SODIUM AND POTASSIUM ESSENTIAL FOR LIFE LITHIUM USED FOR BATTERIES AND MEDICINES

ALKALINE EARTH GROUP 2 NOT AS REACTIVE AS 1 BUT STILL MORE REACTIVE THAN OTHER METALS FOUND IN NATURE IN COMPOUNDS TWO VALENCE ELECTRONS MAGNESIUM COMBINE WITH ALUMINUM MAKE ALLOY FOR LADDERS AND AIRPLANE PARTS CALCIUM ESSENTIAL FOR HEALTH

TRANSITIONAL METALS GROUP 3 TO 12 IN THE VALLEY FORMS THE BRIDGE BETWEEN THE VERY REACTIVE METALS AND THE LESS REACTIVE MOST ARE HARD AND SHINY GOOD CONDUCTORS OF ELECTRICITY FAIRLY STABLE REACTING SLOWLY OR NOT AT ALL WITH AIR AND WATER

RARE EARTH METALS LANTHANIDES ACTINIDES SOFT, MALLEABLE, SHINY HIGH CONDUCTIVITY USED IN INDUSTRY IN VARIETY OF ALLOYS ACTINIDES Found in small quantities Nuclear energy After 92 they are man made They break apart quickly Atom is unstable

Name the family Cobalt potassium Lithium silver Calcium cerium Magnesium tungsten Iron cesium Uranium nickel Einsteinium zirconium Mercury zinc Barium plutonium Francium strontium

NONMETALS LOCATED TO THE RIGHT OF THE ZIGZAG LINE PHYSICAL PROPERTIES DULL BRITTLE SO NOT MALLEABLE AND NOT DUCTILE LOWER DENSITIES POOR CONDUCTORS OR HEAT AND ELECTRICITY

NONMETALS CHEMICAL PROPERTIES GAIN AND SHARE ELECTRONS METALS AND NONMETALS, GROUP 17, FORM SALT NONMETALS BONDS WITH ITSELF IT CREATES A MOLECULE CALLED A DIATOMIC MOLECULES

BORON FAMILY BORON ARE METALLOID ALUMINUM IS A METAL THE REST ARE METALS THREE VALENCE ELECTRON BORON USED AS DETERGENT, CLEANING AGENTS ALUMINUM USED IN CANS AN AS ALLOY FOR AIRPLANE PARTS

CARBON FAMILY FOUR VALENCE ELECTRONS CARBON IS NON SILICON AND GERMANIUM ARE METALLOIDS TIN AND LEAD ARE METALS ALL LIVING THINGS CONTAIN CARBON

NITROGEN FAMILY FIVE VALENCE ELECTRONS NONMETALS ARE NITROGEN AND PHOSPHORUS 80% NITROGEN IN ATMOSPHERE NITROGEN FIXATION IS THE PROCESS THAT ORGANISMS LIKE BACTERIA COMBINE OXYGEN WITH OTHERS ELEMENTS SO LIVING THINGS CAN USE IT

OXYGEN 6 VALENCE ELECTRONS FORM DIATOMIC MOLECULES ESSENTIAL FOR LIFE FOR CHEMICAL REACTIONS SHUT UP O IS THE MOST COMMON ELEMENT IN THE EARTHS CRUST SECOND MOST IN THE ATMOSPHERE SULFUR MAKE A ROTTEN EGG SMELL AND IS FOR EXPLOSIVE MATERIALS AND MEDICINES

HALOGENS 7 VALENCE ELECTRONS MOST REACTIVE NON METALS F FOR TOOTHPASTE AND NON STICK COOKWARE Cl FOR SALTS AND POOLS I DISINFECTANT

NOBLE GASES VALENCE ELECTRONS 8 FULL OUTER SHELL CAN’T COMBINE WITH EASILY WITH OTHER ELEMENTS ALL NON METALS
