WebThe radii are in . For ions of the same charge, the ionic radius increases as you go down any column because the elements of higher atomic number have a greater number of … WebIonic radius: The distance between the nucleus and the electron in an ion’s outermost shell is called the ionic radius. Conclusion The ionic radius increases on descending the group and decreases on going across a period and it is applicable only if the elements are the same type of ion, either cations or anions.
WebAn anion has an extra electron, which increases the size of the electron cloud and may cause the ionic radius to be larger than the atomic radius. An anion’s radius may be … WebD) Br-.

WebThe ionic radius increases on decending a group as would be expected with the increasing number of electron shells. Ionic Radius Trends top Isoelectronic particles … Ions may be larger or smaller than the neutral atom, depending on the ion's electric charge. When an atom loses an electron to form a cation, the other electrons are more attracted to the nucleus, and the radius of the ion gets smaller. Similarly, when an electron is added to an atom, forming an anion, the added electron increases the size of the electron cloud by interelectronic repul…
