Question

If the size of a nucleus is 10^-15 m is scaled up to the tip of a sharp pin (=10^-5m), then what roughly is the size of the atom

Answer 1

since the calculated size of the hydrogen atom which is the smallest atom is 10^-10m and the nucleus is one Fermi therefore the size of this atom must be about 10^-10m

Answer 2

Size of the atom is 10^-10 m
