Step 3:Identify all isotopes of the element. When we look up iron isotopes, we see that there are four main isotopes of iron. They have masses of 54, 56, 57, and 58 amu. We can also see that the major isotope is 56, with an abundance of about 92%. ...
The launch of the Herschel Space Telescope in 2009 finally allowed scientists to identify a type of noble gas molecule in space. Herschel captured data by tracking infrared radiation, and when it turned its attention to the Crab Nebula, something strange happened. The data showed a molecule in ...

To identify the collective transport mode leading to the T1/2 temperature dependence dominant above 0.5 K, let us compare it with two other cases. In crystals, the cubic temperature dependence of phonons at low temperature reflects the temperature dependence of the volume of the Debye sphere when...
Therefore, isotope anomalies with very small magnitudes (ppm-level), such as W, has been used to identify different mantle reservoirs, the time scales of their formation and potential core-mantle interactions. W anomalies are generally considered as the sole consequences of radioactivity and ...
We identify uncertainties and knowledge gaps of chemical risk assessment related to unconventional drillings and propose adaptations. We discuss how chemical risk assessment in the context of unconventional oil and gas (UO&G) activities differs from conventional chemical risk assessment and the implications...

OK, I took my sample into my brother's lab to test its density.We measured its volume by dropping it in a full beaker of water and measuring the weight (and thus volume) of the water that was displaced on a microgram scale. By far the biggest problems we had were: - eliminating ...
You are probably aware that numbers are used every day to identify people and objects. 日常生活中我们对人和物体计数。 For example, people can be identified by their Social Security numbers and computers by their IP addresses. Atoms and nuclei are also identified by numbers. ...
