A giant Atom literally

[Huesito88]

Ok say in a story there's this character (let's call him D) that has a beam that can increase the size of various objects. He can use it on himself which results in him becoming 100 foot tall and weighs a lot. D then uses it on a single Atom causing it to be huge, having a 10 meter long diameter now.

Now how much does this giant Atom weigh is there a way to calculate it? Are we allowed to assume the nucleus grows proportionate in size too? If so for the latter than would we also be able to use the 2.3×10^17 KG/M^3 Density value of the Nucleus, what about using 10^35 Pa pressure of a Proton?

D then uses it on a single Atom causing it to be huge, having a 10 meter long diameter now.

Using a hydrogen atom as an example for this.

The diamaeter of a hydrogen atom is approximately 1.06e-10 m and the nucleus has a diameter of approximately 2.4e-15 m going by this site.

The difference between the end diameter and the starting diameter is: 10 m / 1.06e-10 m = 9.4339623e-10

So scaling up nucleus diameter would then be: 2.4e-15 * 9.43e10 = 2.26e-4 or 0.000226 meters. So the radius would be half of that at 0.000113 meters.

The volume of the scaled up nucleus (assuming a sphere) would be: 4/3 * Pi * 0.000113^3 = 6.0439928e-12 m^3.

If we use that 2.3e17 KG/M^3 density figure you've provided, then it's: 6.0439928e-12 * 2.3e17 = 1390118.344 kilograms.

1390118.344 kg = 1390.118344 meteric tons.
