Which is more stable pure metal or its ore?

Pure metal is more stable than its ore because ores are compounds that contain the metal combined with other elements. In order to obtain pure metal from an ore, the ore needs to undergo chemical processes like reduction or electrolysis. This means that pure metal has a higher energy state compared to ores, making it more stable.


Why was gold discovered earlier than iron?

- gold has a very specific and beautiful color, easily to identify - gold is not corroded - gold is a mineral as a pure metal


Which pure metal has more restivity?

silver


Can a 100 percent pure metal get corrod?

yes, a 100 percent pure metal can get corroded. corrosion is a surface phenomena. pure metals are likely to get corroded than the metals with some impurity. for example, aluminum in its purest form (say 100 %) gets corroded easily but when aluminum is exposed to air it forms a thin layer of alumina which in turn prevents the inner layers to get corroded (now purity of aluminum has decreased, say 95%). hence corrosion has got its useful side too!


Is an electroplated metal more conductive?

Not necessarily. The conductivity depends on what metal it is and how pure it is.


In what way is an alloy better than a metal in pure form?

An alloy is better than a metal in pure form in the way that an alloy contains some extra materials possessing some different properties which would prevent it from getting corroded easily and thus increase its life span for using purposes.


Why does manufacturing alloys make a more beneficial metal?

Alloys have improved mechanical properties, hardness, resistance to corrosion, resistance to heating, stable crystalline structure etc. compared with pure metals.


Is alloy or a pure metal?

pure metal


What is the similar between pure metals and alloys?

A pure metal contains only one metal while an alloy is a mixture of two or more metals.


Why do metals combine with oxygen?

Metals combine with oxygen to form metal oxides in a process called oxidation. This occurs because metals have a tendency to lose electrons, forming positive ions, while oxygen has a high affinity for gaining electrons. The resulting metal oxides are more stable compounds compared to the pure metal.


Why Are stop signs are octagon shaped?

Getting more out of the metal. Pure economics.


Is this statement true or false a pure metal like an alloy contains no nonmetallic elements?

No! A alloy can be a number of different materials plus one or more metal. A pure metal like the element Cu copper does not have any other matter in it besides itself
