Almost all of the mass (more than 99%) of an atom is contained in the dense nucleus. An atomic nucleus is much, much smaller than an atom. The cloud of electrons that "orbit" the nucleus and define the "size" of an atom is roughly100,000 times as large as that atom's nucleus!

Answer:

260 times bigger

Explanation:

Let's make some assumptions:

Let's assume the earth represented an atom. Assume that the diameter of an atom is 5 × 10⁴ greater than the diameter of the nucleus. Diameter of earth is 1.37×10⁴

Therefore,

Diameter of the model nucleus = diameter of earth/5×10⁴

Diameter of nucleus = 1.37×10⁴/5×10⁴

= 260m
