History of Helium Discovery
In the late 1860s, French astronomer Jules Janssen and English astronomer Joseph Norman Lockyer independently observed a yellow spectral line in the sun's light during solar eclipses. This unique line did not correspond to any known element. It was later named the "D3" line and attributed to an undiscovered element.
However, it wasn't until 1895 that Scottish chemist Sir William Ramsay and English chemist Lord Rayleigh discovered helium on Earth. They identified it as a new element while studying a uranium mineral called cleveite. This find marked the first terrestrial detection of helium, shedding light on its presence beyond astronomical observations.
Helium Properties and Uses
Helium, represented by the symbol He, is distinguished as the second lightest and second most abundant element in the observable universe after hydrogen. Its inert properties make it a noble gas, rendering it non-reactive under normal conditions.
The remarkable characteristics of helium have led to its extensive use in various applications. It is a crucial coolant in cryogenics because of its low boiling point. Its low boiling point makes it indispensable for maintaining superconducting temperatures in scientific research and medical imaging equipment such as MRI machines.
Helium is pivotal in welding processes as a shielding gas, particularly in TIG (Tungsten Inert Gas) welding. Its inert nature ensures arc stability and prevents atmospheric contamination during welding operations, contributing to high-quality welds with minimal defects.
