The number of electrons in an atom varies from element to element. A hydrogen atomm, for example, only has one electron. An oxygen atom has eight, while a potassium atom has nineteen. With so many varying quantities of so many different substances in the human body, the question is unanswerable.

We know the average composition of a human body. So, based on this we can calculate the number of atoms of each element and, therefore, the number of electrons. To calculate this number I started with the composition of a 70 kg human (http://web2.airmail.net/uthman/elements_of_body.html). I then used the following equation to calculate the number of electron contributed by each element: Atomic # x mass of element (g) x Avagodro's # (atoms/mol) / Atomic Weight (g/mol) I then took the sum of these values and got 2.2320370181851 x 10^28 electrons in a 70 kg human.
