We read about a lot of gases in our atmosphere. Oxygen is crucial for us because it supports life and also triggers combustion. Similarly, carbon-di-oxide has several industrial applications too.
Nitrogen supports plant food and growth and provides an optimum environment for plant growth. These three gases are commonly found in our atmosphere.
However, these are not noble gases because they do not have a full outer orbit. So, they are pretty reactive, and that’s why they are used in several laboratory experiments. On the other hand, Noble gases always find the last spot on the row in the periodic table.
In this article, we throw some light on the uses of noble gases.
What are noble gases?
When we write the atomic table for every element, we look at the number of electrons missing to make an element stable. Hence, the element is ready to react with other elements to form more stable molecules. Noble gases, on the other hand, are inert in nature.
This means they are chemically unreactive. This is because their last orbit is completely full. A satisfied orbit denotes that the element does not need to seek stability externally. Hence, noble gases are very stable, and they do not react with other elements easily.
List of noble gases with corresponding essential details
Let’s take a look at the noble gases and general information about them. Discussed below is a tabular depiction of that information. The list has been arranged in the order of the periodic table.
|Group No.||Period Number||Noble Gas Element||Atomic Number||Electronic Configuration|

Inert gases have wide applications in several industries. All these uses can be asked as questions in several competitive exams.
Therefore, be mindful of these and learn them if possible. Also, be thorough with the orbital formula of every gas and its inorganic structure. Additionally, learn the periodic table place for these gases for reference.
You can use popular mnemonics to learn the periodic table to make names, atomic numbers, and symbols of the elements handy to remember.
