ZnH2 is an example of?
Correct answer: C. Polymeric hydrides
- A. Metallic hydrides
- B. Complex hydrides
- C. Polymeric hydrides
- D. Borderline hydrides
Explanation
ZnH₂ does not exist as simple Zn-H units.Instead, it forms a polymeric structure where hydrogen atoms act as bridges between zinc atoms (Zn-H-Zn). This extended network is characteristic of polymeric hydrides, commonly formed by metals near the borderline between ionic and covalent behavior.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
