Answer:
An electron is about 10^-18m wide (this is an average, since the size of an electron isnt constant) and a hydrogen atom is about 10^-10m (again this is an average, since hydrogen atoms take on diffrent sizes depending on the othet atom it has formed a chemical bond with).
So there is a diffrence of about 10^8, or about 1,000,000,000. The hydrogen atom is one billion times larger than a single electron
