      I am not a physicist, but from doing an internet search, there are approximately 7 x 1027 atoms in the average human body, based on a 70kg adult human male. Generally, a smaller person would contain fewer atoms; a larger person would contain more atoms. So in a foot, there would be fewer atoms, but still an awful lot!
