8 An atom of lead has a radius of 154. pm and the average orbital speed of the electrons in it is about 1.8 × 10³ m/s. Calculate the least possible uncertainty in a measurement of the speed of an electron in an atom of lead. Write your answer as a percentage of the average speed, and round it to 2 significant digits.
