When the potassium channels open and potassium ions diffuse OUT of the cell, the intracellular potential becomes negative.  
Because of this negative potential, part of the diffused ions are pulled back into the cell.

The electric force of the negative intracellular membrane potential moves potassium (K<sup>+</sup>) {=from outside to inside.~from inside to outside} of the cell.
//LEVEL:3 
//RAND 
When the potassium (K<sup>+</sup>) channel is open, the diffusion continues until there is no difference in concentration between inside and outside the cell. {~true.=false}
