Can XRF Detect Chlorine? The XRF sensor can only detect the possibility of PCB contamination. It detects chlorine, but it cannot differentiate between the two chlorine species. Therefore, if chlorine is found further tests must be conducted to determine if the chlorinated compounds are PCBs. What elements can be detected with XRF? XRF (and particularly
Where Do Elements Are Being Formed? The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, however, are only formed in the massive stars which end their lives in supernova explosions. Where are elements formed? Almost
Where Did All Heavy Elements In The Sun Come From? Most heavy elements were formed in heavy stars of previous generations, that exploded in supernovae and spread them into the interstellar medium. From that medium the Sun formed, this is why it contains heavy elements (only about 1.5% in mass). Where did the elements in
What Evidence Do We Have That The Sun Contains The Element Iron? What evidence do we have that the Sun contains the element iron? Solar spectra show absorption in spectral lines that are characteristic of iron and are unique to it. Where did the iron in our solar system come from? Iron is made inside
How Are Elements Heavier Than Beryllium Formed? Elements heavier than beryllium are formed through stellar nucleosynthesis. Stellar nucleosynthesis is the process by which elements are formed within stars. The abundances of these elements change as the stars evolve. How do elements heavier than beryllium but lighter than iron formed? In turn, the fusion of beryllium
What Element Is Most Common In A Star? What element is most common in a star? Hydrogen. Hydrogen is the most abundant element in the universe and makes up three-quarters of all matter. Stars form when huge amounts of gas and dust collapse under their own gravitational force. The majority of this gas is hydrogen
