There is a higher concentration of ions outside the cell, while ions are more abundant inside the cell. As a result, ions want to diffuse from outside into the cell and ions want to diffuse from inside to outside of the cell.

There is a higher concentration of Sodium ions outside the cell, while Potassium ions are more abundant inside the cell. As a result, Potassium ions want to diffuse from outside into the cell and Sodium ions want to diffuse from inside to outside of the cell

Explanation:

Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration.

Cell’s membrane potential is determined relatively by various types of ion channels open at resting stage. In neuroglia cells, at resting stage cell membrane is “relatively more permeable to potassium ion (K+) than any other ions”, as a result K+ accumulates inside the cells. However because of concentration gradient K+ also starts moving out of the cell.
