D-Block Group Copper- Cu Zinc- Zn Silver- Ag Cadmium- Cd Gold- Au Mercury- Hg • Transition Metals • Group 11 and 12 • Formula(Cu,Ag,& Au)- nD9 • Formula(Zn, Cd, & Hg)- nD10 • Where n begins at 3 and ends at 5!
Chemical Properties • Copper- reactive • Silver- inert • Gold- inert • Zinc- reactive • Cadmium- reactive • Mercury- inert Reactivity changes within the group. Reactivity of an element depends on the electrons in the outermost shell.
Copper • USES • 65% for electrical purposes • 24% for construction • Coins • Can be found as native copper or part of a mineral • FUN FACTS • Statue of Liberty is made of more than 8o tons of copper • 80% of all copper produced is still being used through recycling • Gold is so soft that a little copper is always added
Silver • Silver is found in native form, as an alloy with gold and in ores • FUN FACTS • Best conductor of all elements • Throughout history more people have silver for money over gold • Peru and Mexico are largest producers • USES • Jewelry • Currency • Photography • Dentistry • Conductor
Gold • FUN FACTS • Gold about the size of your thumbnail can spread to fit a tennis court • Only metal that does not rust • One of the softest metals • Occurs naturally in nature • USES • Jewelry • Coins • Silverware/ Plates • Awards • Dentistry
Zinc • FUN FACTS • Last element alphabetically • In the body, can maximize physical growth and development • 1 of 4 one syllable elements • The element is normally found in association with other basemetals such as copper and lead in ores • USES • Galvanize other metals to prevent corrosion • Paints • Rubber Products
Cadmium • Found only in compounds • FUN FACTS • Associated with TV’s • It is toxic • Almost all is contained by a by-pruduct • USES • Mostly in batteries • Electroplating
Mercury • Found both by itself and as a compound in nature FUN FACTS • So thick that bricks can float in it • Gold dissolves in it • Very toxic • Liquid metal • USES • Thermometers • Barometers • For production of chlorine
