Group+11Hr7

Group 11 "The Coin Group!" This group contains: GOLD COPPER AND SILVER Physical Properties: 1.) Ductile 2.) Malleable 3.) Conductors of Electricity

Chemical Properties: 1.)Not Reactive 2.)Tarnishes over time, but is able to be cleaned 3.) Reacts with certain elements to form compounds such as chloride bromine and oxygen most commonly

Periodic Trends: 1.)Get less reactive as you descend the period 2.)Density increases as you descend the period 3.)Become less manageable as you descend the period (less workable)
