Reactivity of metals

1. Reactivity of metals By: Ghada Al-Kuwari

2. What are metals? A metal is a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals. in chemistry, a metal is an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions. Those ions are surrounded by delocalized electrons, which are responsible for the conductivity. The solid thus produced is held by electrostatic interactions between the ions and the electron clouds, which are called metallic bonds.

3. The Reactivity Series Not at all Reactive

4. Not very Reactive

5. Fairly Reactive

6. Very Reactive

8. Is there a relationship? Yes, There is a relationship between the metals gold and silver. It examines the long run trend between the prices of gold and silver futures contracts traded on the Tokyo Commodity Exchange and concludes that the stable relationship between gold and silver prices has disappeared in the 1990s. Gold is more expensive then silver a lot.
