Class 11 inert gas radii- Inert gases, also known as noble gases, are a group of elements in Group 18 of the periodic table. The inert gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These gases are characterized by their stable electronic configurations and lack of reactivity under normal conditions.
The atomic radii of inert gases generally increase as you move down the group. This is because each successive element has an additional electron shell, leading to an increase in the size of the atomic radius. The atomic radii of the inert gases in Class 11 (or the 11th group of the periodic table) are as follows:
- Helium (He): Atomic radius is not typically defined for helium due to its small size and unique characteristics. Helium has only two electrons, filling its first and only electron shell.
- Neon (Ne): Neon has a larger atomic radius compared to helium. As you move down the group, additional electron shells are added. Neon has two electron shells.
- Argon (Ar): Argon is larger than neon because it has another electron shell. It has three electron shells.
- Krypton (Kr): Krypton is larger than argon, with four electron shells.
- Xenon (Xe): Xenon is larger than krypton, with five electron shells.
- Radon (Rn): Radon is the largest inert gas in the group with six electron shells.
Remember that atomic radii are measured in picometers (pm) or angstroms (ร ). The trend of increasing atomic radii down the group holds for most elements in the periodic table. Keep in mind that the values can vary slightly depending on the method used to determine atomic radii and the specific conditions under which measurements are made.
What is Required Class 11 inert gas radii
“Inert gas radii” typically refers to the atomic radii of inert gases, also known as noble gases. Inert gases are elements found in Group 18 of the periodic table, and they include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
The atomic radius is a measure of the size of an atom, usually defined as the distance from the nucleus to the outermost electron shell. For inert gases, the atomic radii generally increase as you move down the group. This is because each successive element has an additional electron shell, leading to an increase in the size of the atomic radius.
Here’s a general trend in inert gas atomic radii:
- Helium (He): Smallest atomic radius.
- Neon (Ne): Larger than helium, but still relatively small.
- Argon (Ar): Larger than neon.
- Krypton (Kr): Larger than argon.
- Xenon (Xe): Larger than krypton.
- Radon (Rn): Largest atomic radius among the inert gases.
It’s important to note that atomic radii are not fixed values; they can vary depending on the method used for measurement and the specific conditions under which the measurements are made. The trend mentioned above is a generalization based on the periodic table trends.
Who is Required Class 11 inert gas radii
“Inert gas radii” is not a term that refers to a person; rather, it is a phrase related to chemistry and the study of the sizes (radii) of atoms of inert gases, also known as noble gases. Inert gases, which include helium, neon, argon, krypton, xenon, and radon, are elements in Group 18 of the periodic table.
The phrase “inert gas radii” specifically refers to the atomic radii of these inert gases. Atomic radius is a measure of the size of an atom, usually defined as the distance from the nucleus to the outermost electron shell. The atomic radii of inert gases generally increase as you move down the group in the periodic table.

When is Required Class 11 inert gas radii
If you are asking about when the study of inert gas radii typically occurs in a chemistry curriculum, it is usually covered as part of the periodic table trends and properties of elements. In most high school or introductory college chemistry courses, the topic of atomic radii, including those of inert gases (noble gases), is discussed when learning about the periodic table.
The trends in atomic radii, including the increase in size down a group, are important aspects of understanding the periodicity of elements. Inert gases are particularly interesting because they are found in Group 18 of the periodic table and have a unique stability due to their filled electron shells.
The specific timing of when this topic is covered can vary depending on the curriculum and educational system. Generally, it is a part of the early sections of a chemistry course that covers the fundamentals of atomic structure and the periodic table. If you have a specific educational context or curriculum in mind, it may be helpful to refer to your course syllabus or curriculum guidelines for precise information.
Where is Required Class 11 inert gas radii
The term “inert gas radii” refers to the atomic radii of inert gases, also known as noble gases. The inert gases are found in Group 18 of the periodic table. The specific inert gases include:
- Helium (He)
- Neon (Ne)
- Argon (Ar)
- Krypton (Kr)
- Xenon (Xe)
- Radon (Rn)
In terms of their location on the periodic table:
- Helium is the first element in the group and the topmost element in the periodic table.
- Neon is next to helium.
- Argon is the third element in the group, following neon.
- Krypton is fourth.
- Xenon is fifth.
- Radon is sixth and is the bottommost element in the group.
The atomic radii of these inert gases generally increase as you move down the group, following the trend seen in the periodic table. This trend is due to the addition of electron shells as you go from one inert gas to the next down the group.
How is Required Class 11 inert gas radii
The inert gas radii, or atomic radii of inert gases (noble gases), follow certain trends on the periodic table. Here’s a general overview:
- Helium (He): Helium is the smallest inert gas with the smallest atomic radius. It has only two electrons in its outer shell.
- Neon (Ne): Neon is larger than helium because it has more electrons and occupies an additional electron shell.
- Argon (Ar): Argon is larger than neon, and it continues the trend of having additional electron shells.
- Krypton (Kr): Krypton is larger than argon, and it follows the trend of increasing atomic size as you move down the group.
- Xenon (Xe): Xenon is larger than krypton, with additional electron shells.
- Radon (Rn): Radon is the largest inert gas in terms of atomic size among the noble gases. It has the most electron shells.
The general trend is an increase in atomic size as you move down the group of inert gases. This is because each successive element in the group has an additional electron shell, leading to an increase in the overall size of the atom.
It’s important to note that atomic radii are measured in picometers (pm) or angstroms (ร ) and can vary slightly depending on the method of measurement and the specific conditions under which the measurements are made.

While the atomic radii of inert gases (noble gases) may not have direct industrial applications, the unique properties of these gases find various uses in industrial processes. Below are some industrial applications where inert gases, with their specific characteristics related to atomic radii, play crucial roles:
- Welding:
- Inert gases, particularly argon and helium, are commonly used as shielding gases in welding processes. Their inert nature helps prevent oxidation and other chemical reactions during the welding process, creating a stable environment for high-quality welds.
