SUMMARY
The discussion focuses on calculating the number of excess electrons on a ball with a charge of -4.00 x 10^-17 C. The correct method involves dividing the total charge by the charge of a single electron, which is 1.60 x 10^-19 C. The accurate calculation yields 2.5 x 10^2 electrons, confirming that charge is quantized and must be a multiple of the elementary charge. Participants clarified the division of powers of ten and the significance of negative exponents in this context.
