Apparently helium is the second-most abundant element in the universe (while hydrogen is first). Where is helium found on Earth?<\/p>\n
It turns out that most helium is commercially obtained from natural gas wells (believe it or not): in fact, natural gas can be up to 7% helium.<\/p>\n
Why is helium found in natural gas? An idea is that, as uranium and thorium undergo α decay, helium results (see yesterday’s post<\/a>). It may then get trapped underground like any other gas, so is found with natural gas.<\/p>\n Gas wells in the south-central US, as well as Wyoming, can be quite productive of helium.<\/p>\n Source:<\/p>\n geology.com<\/a><\/p>\n rsc.org<\/a><\/p>\nJack of Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC.\n","protected":false},"excerpt":{"rendered":" Self-tutoring about chemistry: the tutor learns about helium and its sources on Earth.
