Concept explainers
Interpretation:
The ion with largest radius should be identified and explain the reason.
O2-, F- ,F.
Concept Introduction:
There are two terms for measurement which is used to explain atomic size is ionic radius and atomic radius. Atomic radius is defined as the distance from the nucleus to the outermost electron (stable) of neutral atom. Ionic radius is defined as the half the distance between two gaseous atoms which are just so closely located or touching each other.
If an atom loses its outermost electrons said to be cation, then the atomic radius is larger than the ionic radius as an atom loses a shell of electron energy. If an atom gains an electrons said to be anion, then the size of both atomic and ionic radius is comparable as the electron falls into an existing shell of energy.
