Final answer:
The radius of the electron cloud is about 100,000 times larger than the radius of the nucleus.
Step-by-step explanation:
The radius of the electron cloud is about 100,000 times larger than the radius of the nucleus.
The nucleus of an atom is extremely small, with a diameter of about 10-14 meters. On the other hand, the electron cloud surrounding the nucleus is much larger, with a diameter of about 10-10 meters. This means that the electron cloud is about 100,000 times larger than the nucleus.
For example, if an atom were the size of a football stadium, the nucleus would be about the size of a pea, while the electron cloud would extend far beyond the stadium.
