Embibe Experts Solutions for Chapter: Atoms, Molecules and Nuclei, Exercise 1: Exercise 1

Assertion: Neutrons penetrate matter more readily as compared to protons.

Reason: Neutrons are slightly more massive than protons.

The ionization potential of hydrogenic ions $P$ and $Q$ are $V_{\mathrm{P}}$ and $V_{\mathrm{Q}}$ respectively. If $V_{\mathrm{Q}}<V_{\mathrm{P}}$ then radii
