Microhardness is a hardness test used to check lightweight metals and alloys. Sometimes referred to as micro-indentation testing, these test use very light loads to make a microscopic impression.
yes they are metals
Noble metals and precious metals can be the same thing. Noble metals are known for their usefulness in the industrial fields. They resist corrosion and oxidation. Precious metals fit this description, but are also aesthetically appealing and desirable, giving them value outside the manufacturing realm.
whic combination of metals cannooot be used in a bi metallic strip
copper & steel
All the transition state metals can be found in the clearly marked central portion of the periodic table of elements, but I will tell you that most of the well-known metals, such as iron, copper, gold, lead, zinc, nickel, chromium, platinum, etc., are transition state elements. The only really well known metal that is not a transition state element is aluminum. Other metals such as calcium or sodium are also not transition state elements, but they are not often encountered in their metallic form, they are encountered in compounds such as salt. Metals that we encounter in metallic form are almost always transition state elements.
What is the important of microhardness test
David Richard Bourne has written: 'The microhardness and chemical reactivity of Lanthanide dicarbide solid solutions'
what are the characteristics of metals? metals? non-metals?
metals
They are metals.
Alkali metals are very reactive metals.
They are in between the metals and non metals
You can see the Alkaline Metals, Alkaline Earth Metals, Transition Metals, Other Metals (poor conducting metals), metaloids (characteristics of metals and non-metals combined), non-metals, noble gases, and unknown metals (like #112-118)The transition metals at the bottom of the periodic table are lanthanides and actinides.3 main ones are usually: Alkaline metals, Transition metals, and Non-metals...I hope this was useful!-Fuyuki
I believe that the answer you are looking for is Transition Metals.
