Sodium and chloride also help to determine the resting potential. Sodium is positive and has a concentration gradient set up to flow INTO the cell, and chloride is negative and has a concentration gradient set up to flow INTO the cell. The resting conductance for these two ions is less than that of potassium, but is not zero. Their story (concentration gradient + electrical gradient) is very similar to that of potassium. These ions together determine the resting potential of the cell.
