WebThe addition of a proton to a hydrogen atom to become helium is an example of a chemical reaction. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer See … Numerous researchers attempted to create chemical compounds of helium in the early part of the twentieth century. In 1895 L. Troost and L. Ouvrard believed they had witnessed a reaction between magnesium vapour and helium (and also argon) due to the spectrum of helium disappearing from the tube they were passing it through. In 1906, W. Ternant Cooke claimed to have noticed a reaction of helium with cadmium or mercury vapour by observing an increase in th… Web13 jun. 2016 · Helium doesn't form any compounds, being a noble gas. That is, you can't extract it from any reaction, because you don't have anything that it reacted with already. Also, it would've probably taken much more energy to form that helium compound than it would've to actually extracted it from the atmosphere. Now, you can produce helium, … maloja clothing canada
