compared to a grain of salt or something common.

A hydrogen atom is (including the electron orbital) about
1.20 Angstrom
A grain of salt is about
0.5 mm
(google search on "size of grain of salt")
1 Angstrom is 1*10^-10 m (http://en.wikipedia.org/wiki/Angstrom)
So a typical grain of salt is 4,170,000 times bigger.
So reversing it, the equivalent would be a grain of salt compared to 2.085 kilometers.

The first answer is right about the size.
A hydrogen atom has exactly one proton
in the nucleus. The most common form
(some call protium) has no neutrons.
Deuterium is an isotope of hydrogen with one neutron
added to the nucleus and tritium has two neutrons
in addition to the proton.

The proton's size is of order 10^-15 meters.

All ATOMS have protons and nuetrons in the middle
