Helium and Neon – About Elements

Helium

It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.

Neon

Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.

Helium and Neon – Applications

Helium

Helium is used for many purposes that require some of its unique properties, such as its low boiling point, low density, low solubility, high thermal conductivity, or inertness. Of the 2014 world helium total production of about 32 million kg (180 million standard cubic meters) helium per year, the largest use (about 32% of the total in 2014) is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners and NMR spectrometers. Most clinical magnets are superconducting magnets, which require liquid helium to keep them very cold.

Neon

Neon is often used in signs and produces an unmistakable bright reddish-orange light. Although tube lights with other colors are often called “neon”, they use different noble gases or varied colors of fluorescent lighting. Neon is also used to make high-voltage indicators and switching gear, lightning arresters, diving equipment and lasers. Liquid neon is an important cryogenic refrigerant. It has over 40 times more refrigerating capacity per unit volume than liquid helium, and more than 3 times that of liquid hydrogen
