Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Covalent solids
Concept:
Solids can be classified by the type of particles that occupy their lattice points.

Solution:
  • In a covalent solid (also known as a network solid), the lattice points are occupied by neutral, individual atoms (e.g., Carbon atoms in diamond or Silicon/Oxygen in quartz).
  • Because their structural particles are purely neutral atoms bonded via a continuous network of covalent bonds, they are frequently termed atomic solids.


Why other options are incorrect:
  • B: Ionic solids have cations and anions at their lattice points.
  • C: Metallic solids have positive metal kernels immersed in a sea of electrons.
  • D: Molecular solids have discrete molecules (like \( \text{I}_2 \) or \( \text{H}_2\text{O} \)) at their lattice points.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
