What type of ions are present in the axoplasm of a resting neuron?

What type of ions are present in the axoplasm of a resting neuron?
  1. High concentration of sodium ions (Na⁺) and low concentration of potassium ions (K⁺).
  2. Low concentration of sodium ions (Na⁺) and high concentration of potassium ions (K⁺).
  3. High concentration of positively charged proteins and low concentration of negatively charged proteins.
  4. Low concentration of positively charged proteins and high concentration of negatively charged proteins.

Solution

When a neuron is resting, the axonal membrane is more permeable to potassium ions (K⁺) and nearly impermeable to sodium ions (Na⁺). The axoplasm inside the
