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.
Neon is a rare atmospheric gas and as such is non-toxic and chemically inert. Neon poses no threat to the environment, and can have no impact at all because it's chemically unreactive and forms no compounds. No known ecological damage caused by this element.
First of all, even though we need to breathe oxygen to survive, oxygen is not the most abundant
gas in the atmosphere. Nitrogen is, by far.

The components used to make a neon sign are quite costly. As a result, neon sign makers pass these costs on to buyers at a markup which results in higher prices. Furthermore, the cost of the components is not limited to just buying them, handling them may equally be expensive.
How is neon used today? Neon is used in lighting signs that are often called "neon" signs. Other applications that use neon include lasers, television tubes, and vacuum tubes. The liquid form of neon is used for refrigeration and is considered a more effective refrigerant than liquid helium.
8 Facts About the Element Neon
- The element neon wasn't William Ramsay's first big discovery.
- It's one of the noble gases.
- The name means new.
- It's pulled out of the air.
- It glows red.
- It quickly became a lighting element.
- It made it to California before Las Vegas.
- It's for more than just signs.
As the air warms, each element in air changes from a liquid back to a gas at a different temperature. The portion of air that changes back to a gas at -245.92°C is neon.
According to Minerals Education Coalition, neon is primarily obtained from liquefying air. Neon has the smallest temperature range (2.6 degrees C or 4.7 degrees F) for which it is a liquid, according to Chemicool. Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases.

| Silicon | Dull, metallic | Brittle, shatters when shaped |
| Sulfur | Dull | Cannot be stretched |
| Manganese | Shiny | Can be hammered into thin sheets |
Who was Neon discovered by?

William Ramsay
Neon is the tenth element of the periodic table and the second of the noble gases. The element is incredibly non-reactive because of its electron configuration. It has a "happy" electron orbital that is filled with eight electrons.
The key properties of neon include the following:
- It is a colorless, tasteless odorless inert gas.
- It changes to reddish-orange color in vacuum tube.
- It is chemically inactive.
- It has the lowest liquid range of any element.
Neon gas, most commonly found commercially in signs, is trapped in a glass tube with a metal electrode fused on each end. High voltage transformers are attached to the electrodes causing electron transmission. The electrons become accelerated to a high rate of speed.

Neon was discovered in London in 1898 by a pair of British chemists: Sir William Ramsay and Morris W. Travers. Ramsay chilled a sample of air until it became a liquid. He then warmed this liquid, capturing the gases as they boiled off.

Period 2 element
Neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colourless, odourless, tasteless, and lighter than air, neon gas occurs in minute quantities in Earth's atmosphere and trapped within the rocks of Earth's crust.
Neon may be used in the clinical setting as a diagnostic tracer gas in a gas analyzer for a lung diffusion test. Other clinical applications of neon, such as a radiotherapy in various cancers 1, have been studied.
Silicon the semiconductorIt's usually found linked up with a pair of oxygen molecules as silicon dioxide, otherwise known as silica. Quartz, an abundant ingredient in sand, is made up of non-crystallized silica. Silicon is neither metal nor non-metal; it's a metalloid, an element that falls somewhere between the two.
The elements from atomic number 57 to 71 are called Lanthanides. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. The lanthanides are between Barium and Hafnium.

The following acute (short-term) health effects may occur immediately or shortly after exposure to Neon: * Direct skin contact can cause frostbite. * High exposure can cause fatigue, vision disturbance, headache, confusion, dizziness and suffocation from lack of Oxygen.
Neon is important because it is used for lighting, signs, lasers and refrigeration. Neon is the fifth-most abundant element in the universe, but is very rare on Earth. Because it is rare and completely inert, it plays no known role in natural systems or biology.
Health effects of xenonInhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.
Xenon has no known biological role. It is not itself toxic, but its compounds are highly toxic because they are strong oxidising agents. Xenon is present in the atmosphere at a concentration of 0.086 parts per million by volume.
Some individuals experience headache, dizziness, fatigue, nausea and euphoria, and some become unconscious without warning. Loss of consciousness may be accompanied by convulsions and is followed by cyanosis and cardiac arrest. About 7 minutes of oxygen deprivation causes death of the brainstem.
Argon is nontoxic and largely inert. It can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life. Inhalation of argon in excessive amounts can cause dizziness, nausea, vomiting, loss of consciousness, and death.
Krypton is a rare atmospheric gas and as such is non-toxic and chemically inert.
