Question

what is the difference between metals and noble metals and give three example also

Answer 1

Explanation:

The strictest definition of a noble metal is metal with a filled electron d-band. According to this definition, gold, silver, and copper are noble metals. This excludes copper, but adds in other platinum group metals, such as rhodium, palladium, ruthenium, osmium, and iridium.

Answer 2

• A metal (from the Greek word métallon, "mine, quarry, metal") is a glossy substance that transmits electricity and heat quite effectively when newly manufactured, polished, or broken.
• Metals are either malleable (that is, they can be hammered into thin sheets) or ductile (that is, they can be beaten into thin sheets) (can be drawn into wires).
• A metal might be a chemical element like iron, a metal alloy like stainless steel, or a molecular complex like polymeric sulphur nitride.
• Noble metals are metals with exceptional chemical resistance, even at extreme temperatures.
• Catalytic characteristics and the ability to promote or control the rates of chemical processes are well-known.
• Ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), and silver (Au) make up a brief list of chemically noble metals (those elements on which practically all chemists agree)[citation needed] (Ag).
