G. Give two example for each of the following: 1. Metals 2. Alloys 3. Noble metals
Answers
Answer:
In chemistry, noble metals are metallic elements that show outstanding resistance to chemical attack even at high temperatures.[8] They are well known for their catalytic properties and associated capacity to facilitate or control the rates of chemical reactions.[8] The short list of chemically noble metals (those elements upon which almost all chemists agree)[citation needed] comprises ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), silver (Ag).[9] In periodic table terms, an analogy can be made between the noble metals and the noble gases, which are mainly unreactive.[10]
