Formation of Compounds: The Existence of Minerals1.Almost all the Elements in the Earth?s gall ar found in the form of Compounds.

2.Only a fewer Metals such as Gold, Silver and sometimes Copper are found as issue Elements.

3.Minerals are natural Elements or Compounds which have exact/precise/accurate and fixed/ unending chemical composition/content.

4.The above definition of Minerals can cross off Minerals from Rocks which contain various graphic symbols of Minerals.

5.Examples of Minerals which exist in the form of free Elements include Diamond(Carbon), Gold, Platinum, Silver.

6.Most Minerals which exist in the form of Compounds include the Oxides, Sulphides and Carbonates of Metals.

8.Chemical Bonds are strong Electrostatic personable Forces which exist in the midst of Atoms which will enable the Atoms to exist in the form of Clusters, consequently forming Compounds.

9.The type of Bond which is formed depends of the type of Element or the type of Particles which are involved in the formation of the Compound.

Chemical Bonds*Electrostatic Attractive Force ? seductive force which exists between particles with opposite charges.

Examples of Electrostatic Attractive Forces:1.



all-metal Bond2. Ionic Bond3. Covalent Bond1. auriferous BondStructure of Metal:-Many electrons are tie to each Cation by Metallic Bonds.

-Metallic Bonds are also between electrons and Cations in different layers of Metal.

-When a force is applied to the moderate layer of metal atoms, it will only ?slide? a short distance but not all the Metallic Bonds are broken; some are retained to limit the two layers of metal together, allowing the metal to change its shape. ? Ductility and plasticity?Specific Properties of Metals:1.?Ductility? (?Ductile?) ? can be stretched / move into long and thin wires.

2.?Malleability?...
