Detailed Solution

In a resting neuron, the axonal membrane is comparatively more permeable to K⁺.

In a resting neuron, the axonal membrane exhibits greater permeability to potassium ions (K⁺) than sodium ions (Na⁺), primarily due to the abundance of open potassium leak channels. This selective permeability allows potassium to exit the neuron, contributing to the establishment of a negative resting membrane potential. Sodium leak channels are less numerous and less permeable to sodium ions, minimizing their impact on the resting membrane potential. This differential ion permeability is essential for the neuron's ability to generate and propagate electrical signals when stimulated.
