WebThe atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. WebStructure analysis shows that the ionic radius of a metal ion determines the form of the metal centre and the structure of the product. Large metal ions tend to have higher coordination numbers, connect to more bridging ligands …
WebCr 2 O 3 ionic radius. In chromium oxide ionic radius of Cr 3+ is 0.615A 0 and of O 2-is 1.40A 0. Cr 2 O 3 electron configurations. The arrangement of electrons in a particular shell around the nucleus is known as Electronic configuration. Let us study the electronic configuration of Cr 2 O 3. The s, p, d, and f are four orbitals. WebOxidation number of Cr in options A, B, C and D are +6,+4,+3,+3 respectively . In given option, option (A) has highest oxidation number therefore its radii will be smallest. …
