Class 11 ionic radii- In chemistry, ionic radii refer to the size of ions, which are atoms or groups of atoms that have gained or lost electrons. The ionic radius of an ion depends on its electronic configuration and the number of electrons it has gained or lost.
Here are some key points regarding ionic radii for Class 11 chemistry:
- Cations (Positive Ions):
- Cations are formed when an atom loses one or more electrons.
- The removal of electrons reduces the electron-electron repulsion, causing the remaining electrons to be pulled closer to the nucleus.
- As a result, cations are smaller in size compared to their parent atoms.
- Anions (Negative Ions):
- Anions are formed when an atom gains one or more electrons.
- The addition of electrons increases the electron-electron repulsion, causing the electron cloud to expand.
- Therefore, anions are larger in size compared to their parent atoms.
- Periodic Trend:
- Ionic radii follow a periodic trend on the periodic table.
- As you move across a period (from left to right), the ionic radius generally decreases for cations and increases for anions.
- As you move down a group (from top to bottom), the ionic radius generally increases for cations and anions.
- Comparing Ionic Radii:
- When comparing ions of the same charge, the ionic radius increases with an increase in the number of electron shells.
- For ions with the same number of electron shells, the ionic radius decreases with an increase in nuclear charge.
- Isoelectronic Series:
- Isoelectronic species are ions or atoms that have the same number of electrons.
- In an isoelectronic series, the ionic radius decreases with increasing positive charge and increases with increasing negative charge.
It’s important to note that ionic radii are somewhat approximate values and can vary depending on the specific circumstances and the method used to measure them. Additionally, exceptions to the general trends may occur in certain cases.

Who is Required Class 11 ionic radii
“Ionic radii” is a term used in chemistry to describe the size of ions, which are atoms or groups of atoms that have gained or lost electrons. Ionic radii refer to the spatial extent of an ion, and they depend on various factors such as the electronic configuration and the number of electrons gained or lost.
In a general sense, there isn’t a specific person named “ionic radii.” Instead, it’s a concept within the field of chemistry that is studied and understood by students and researchers. When studying chemical bonding, particularly in ionic compounds, understanding the size of ions is crucial for predicting and explaining the properties of these compounds.
