Consider a hypothetical element, Z, which has an atomic number of 122 and is located in a newly discovered row of the periodic table. Element $Z$ forms an oxide, ZO_3, which exhibits both ionic and covalent character. The oxide is a solid at room temperature and has a high melting point. In the context of modern chemical theories, which of the following statements is most likely to be true about the bonding and structure of ZO_3? Options: a) ZO_3 has a molecular structure with $\mathrm{sp}^{\wedge} 2$ hybridization in $\mathrm{Z}$ and forms a lattice similar to silicon dioxide. b) ZO_3 forms a polymeric structure with resonance-stabilized Z-O bonds and has $\mathrm{sp}^{\wedge} 3$ hybridization in Z. c) ZO_3 exhibits a metallic bonding character due to the delocalization of electrons from $Z$ to the oxygen atoms. d) ZO_3 has an ionic lattice with partial covalent character, where $\mathrm{Z}$ exhibits an oxidation state uncommon for its period.

***B*** ∻Key Concept∻ ⚹Hybridization and Polymeric Structure⚹ ∻Explanation∻ ⚹Given the high atomic number of Z (122), it is likely to have access to d and f orbitals, allowing for expanded octets and multiple bonding scenarios. The description of ZO_3 suggests a polymeric structure with resonance stabilization, which is consistent with $\mathrm{sp}^3$ hybridization in Z, as this allows for tetrahedral coordination and resonance in structures similar to phosphates or sulfates.◊What factors contribute to the high melting point of ZO3 with both ionic and covalent character in its bonding?⍭ Generate me a similar question◊⚹
