aye - the Schwarzschild radius of the entire planet is only 8.87 mm. The radius of a 70kg human is 10^12th times smaller than a hydrogen atom. Presuming it is even physically possible for atom massed black holes to exist - hypothetical hydrogen atom black hole would have a radius 10^41 times smaller than a hydrogen atom.

Ultimately the physics of such objects are not well defined, the radius of a hydrogen atom or a proton is defined in terms of electric potentials, calculating the interaction cross section between the quarks in a proton and a hypothetical atom massed black hole is completely ill-defined. At these scales the strong force would dominate - and you'd run into a number of uncomfortable problems which either require hawking radiation to exist or for GR to not conserve energy ( which it doesn't in the classical theory )

but all that being said, whatever collisions created this black hole would surely have left it with a velocity that's a very large fraction of the speed of light.
