Helium is the second most abundant element in the Earth's atmosphere, next to hydrogen. It is a noble gas, which means it does not typically mix with other chemicals and form new compounds. Click for PDF and Google Slides worksheets.
What are the uses of helium gases? Helium gas is used in meteorological functions. It is also used in gas chromatography, cryogenics, and MRI scans due to its low reactivity. What are 3 interesting facts about helium? The three interesting facts about Helium are that: it is an element an...
Helium has the smallest atomic radius of any element, about 0.2 nanometers. So, when it forms and starts moving upward, it can fit through very small pore spaces within the rocks. Halite and anhydrite are the only sedimentary rocks that can block the upward migration of helium atoms. Shales...
in 1895. Ramsay obtained a sample of theuranium-bearing mineral cleveite, and, upon investigating the gas produced by heating the sample, he found that a unique bright yellow line in its spectrum matched that of the D3line observed in the spectrum of the Sun; the new element of helium wa...
