An atomic force microscope (AFM) is an extremely precise microscope that images a sample by rapidly moving a probe with a nanometer-sized tip across its surface. This is quite different than an optical microscope which uses reflected light to image a sample. An AFM probe offers a much higher...
解答一 举报 An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of an atom of 12C.and NA=6.02*10^23therefore ... 解析看不懂?免费查看同类题视频解析查看解答 ...
Lithium is the metal of choice for many solid-state batteries due to the element's high energy density and low binding energy. Structurally, these widely used batteries use lithium ions (Li+) in their cathode and electrolyte, while their anode is often made of graphite or silicon. Why lithiu...
They would also be impossible to counterfeit, since nothing else that’s really usable would be heavy enough. The only other metal challenging its weight is osmium, but as it’s similarly rare nothing would be gained. Moreover osmium presents a hazard in the machine shop iridium doesn't: ...
At room temperature, mercury is not magnetic at all. It has a minimal negative magnetic susceptibility. When you put it in a magnetic field, it will magnetize weakly in the opposite direction. That’s why mercury can be considered a weak diamagnetic substance when exposed to room temperature....
Yes, iron can rust when exposed to oxygen and moisture, forming iron oxide. This process can be prevented through coatings or by alloying iron with other elements. 9 Can iron exist by itself in nature? Iron can be found in its pure form in meteorites, but it's most commonly found as ...
