WebAug 18, 2024 · Figure 7.3. 2: Definitions of the Atomic Radius. (a) The covalent atomic radius, rcov, is half the distance between the nuclei of two like atoms joined by a covalent bond in the same molecule, such as Cl 2. (b) The metallic atomic radius, rmet, is half the distance between the nuclei of two adjacent atoms in a pure solid metal, such as aluminum. WebAnswer (1 of 2): First of all, Br- is not a cation, instead it is an anion. Now when we consider the sizes of Na+, Ca2+ and Al3+, Al3+ is the smallest because of high “effective nuclear charge” (Zeff) . Furthermore, Ca2+ is smaller than Na+ in the same coordination environment. Hence the size of... WebNov 1, 2016 · Answer: Well, I can …. but how?
