    Just simple questions and I need clarifications why is that your answer please.
    1,602 ×10^−19 C write to SI Unit Prefixes

    Let me try and see if I understand your query - you say you have a simple question, but that you would require a detailed response, rather than a short answer. Am I right?

    I'm not really sure what you mean when say 'SI unit prefixes' - perhaps you want to rewrite ##1.602 \times 10^{-19}\ \text{C}## as ##16.02\ \text{atto C}##, or perhaps as ##1\ \text{eV}## ??

    Im sorry, I mean I just want a simple answer and requesting for some explanations why.
    and to your answer, if we will base it on Unit Prefixes. Atto is -18 not -19 , can you explain this? sorry having trouble understanding this part of SI Units.

    Well, ##1.602 \times 10^{-19}\ \text{C} = 1.602 \times 10^{-1} \times 10^{-18}\ \text{C} = 1.602 \times 10^{-1}\ \text{atto C} = 0.1602\ \text{atto C}##.

    So, I was wrong the first time round! o0)

    Oh okay, so if that the case you just have to multiply the excess ?

    Exactly!

    Multiply the excess ##10^{-1}## with ##1.602##. :wink:
