Helium derives its name from the Latin name for the sun. Helium was discovered when spectroscopists found that the 588 nm wavelength (among others) was missing from the sun's spectrum. What is the frequency of this radiation? Enter your response in scientific notation, e.g. enter 2E3 for 2000
Helium comes from the Greek word for sun, helios. That connection to the sun is the reason why, for nearly three decades after it was first observed, chemists dismissed the element that we use today for everything from filling party balloons to cooling the Large Hadron Collider—and now helium is rapidly diminishing.
Sep 28, 2023 · Sir William Ramsay, British physical chemist who discovered four gases (neon, argon, krypton, xenon) and showed that they (with helium and radon) formed an entire family of new elements, the noble gases. He was awarded the 1904 Nobel Prize for Chemistry in recognition of this achievement. Ramsay, Argon (40 Ar), like helium was discovered by LACE during the Apollo 17 mission.
