Question

How does the radius of the electron cloud compare to the radius of the nucleus?

a. It is about 100 times larger
b. It is almost 50 times smaller
c. It is about 50,000 times larger
d. It is about 100,000 times larger

Answer 1

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.
