Have you ever wondered if it’s possible to burn noble gases? I mean, they’re called “noble” for a reason, right? They don’t react with anything, and they’re considered to be the most stable elements on the periodic table. But what if I told you that it’s actually possible to burn these seemingly unreactive gases? Yes, you heard that right! It’s possible to burn noble gases, and it may surprise you to know that it’s due to their very stability that makes it possible.
Now, you may be wondering how noble gases can burn if they don’t react with anything. Well, it turns out that noble gases can be excited and ionized under certain conditions, such as high temperatures or electrical discharge. This causes them to form plasma, which is essentially a high-energy state of matter. So, while the noble gases themselves may not burn, the plasma they form most definitely can. And this is where things start to get interesting.
But what’s the point of burning noble gases? Is there any practical use for it? As a matter of fact, there is. Burning noble gases can be used for a variety of applications, from welding and cutting metals to lighting up neon signs. In fact, neon lights are a prime example of how burning noble gases can be used for a visually stunning effect. When an electrical current is passed through neon gas, it ionizes and emits a bright orange-red glow. So, while you may not have thought much about noble gases before, it’s clear that they have some fascinating properties that are worth exploring.
Properties of Noble Gases
Noble gases are elements that belong to the Group 18 of the periodic table. They are also known as inert gases because of their reluctance to take part in any chemical reaction due to their fully filled outermost shell. The properties of noble gases make them unique and valuable in various fields of science and technology. Some of the significant characteristics of noble gases are as follows:
- Noble gases are odorless, colorless, and tasteless in their stable gaseous state.
- These elements have a low boiling and melting point, and they exist in a gaseous state at room temperature.
- Noble gases are chemically inert and do not react with other elements, except under extreme conditions.
- Their fully filled outermost electron shell makes them stable, and thus, noble gases have very low electronegativity, which means they do not attract electrons.
- Noble gases have a low atomic number, and hence, they are lighter than air, which makes them useful for various applications.

The Unique Characteristics of Nobel Gases
Noble gases are a group of chemical elements from the periodic table – helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). One of the unique characteristics of noble gases is that they are chemically inert, which means they do not react with other elements easily. This is because noble gases have a full outer shell of electrons, which makes them very stable.
Why are Nobel Gases Inert?
- As mentioned earlier, the full outer shell of electrons that noble gases possess makes them very stable, and hence they do not react with other elements easily. For instance, Neon and Helium have only 2 electrons in their valence shell, while the others have eight electrons which make them particularly stable.
- The outermost shell of electrons in noble gases is complete, which means it satisfies the octet rule (where atoms tend to gain or lose electrons in order to have a full outer shell of eight electrons). The noble gases have a complete valence electron shell that neither gains nor loses an electron.
- Noble gases have a weak interatomic bonding between the atoms of the same element in their gaseous state. This weak bonding means that the elements require less energy to break the bond compared to elements with stronger chemical bonds, making it difficult to form chemical compounds with other elements.
Boiling Points and Density of Nobel Gases
Noble gases also have very low boiling points and densities compared to other elements. This is because they have weak molecular forces of attraction between their atoms as well and the low atomic mass of the elements. Below is a table of the boiling points and densities of noble gases.
| Element | Boiling point (°C) | Density (g/L) |
|---|---|---|
| Helium (He) | -268.9 | 0.1785 |
| Neon (Ne) | -246.1 | 0.8999 |
| Argon (Ar) | -185.7 | 1.7837 |
| Krypton (Kr) | -152.3 | 3.749 |
| Xenon (Xe) | -108.1 | 5.894 |
| Radon (Rn) | -61.8 | 9.73 |
In conclusion, noble gases are unique elements with unique characteristics and properties, including their inertness, low boiling point, and density.
The Origins of Noble Gas Names
When it comes to the noble gases, their names are intriguing and diverse. Each noble gas has a unique name that tells a story of how it was discovered and used. Here, we will explore the origins of noble gas names, starting with the three most well-known noble gases: helium, neon, and argon.
- Helium: This noble gas was first discovered on the sun in 1868 by French astronomer Jules Janssen and British astronomer Joseph Norman Lockyer. They named it after the Greek word “Helios,” meaning sun. Helium’s uses have expanded since its discovery, including medical imaging, welding, and rocket fuel.
- Neon: Discovered in 1898 by Scottish chemist Sir William Ramsay and English chemist Morris Travers, neon comes from the Greek word “neos,” meaning new. It was named this because it was the newest noble gas discovered at the time. Neon is widely used in advertising signs and lighting.
- Argon: In 1894, Sir William Ramsay and English physicist John William Strutt, Lord Rayleigh, discovered this noble gas. The name “argon” comes from the Greek word meaning “inactive” or “lazy” as it was believed to have no chemical reactions. Argon is now used as an inert atmosphere in welding and metallurgy, as well as in lighting.
The other noble gases have equally fascinating names. For example, krypton was named after the Greek word “kryptos,” meaning hidden or secret, because of its rarity and difficulty to isolate. Xenon was named from the Greek word “xenos,” meaning stranger or foreigner, as it was the first noble gas discovered that was not already known to exist on Earth. Radon was named after the element radium, from which it was first isolated as a radioactive gas in the early 1900s.
The discovery and naming of noble gases is a testament to the curiosity and ingenuity of scientists throughout history. Their quest to understand the world around us has led to the discovery and naming of these remarkable elements, which continue to play important roles in science and technology today.
