To determine

Why fog or rain droplets tend to form around ions or electrons in the air.

Answer to Problem 3Q

Solution:

Due to polar nature of water molecule (it has a positive region and negative region). Thus, it is easily attracted to some other charged object, like an ion or electron in the air.

Explanation of Solution

Water is polar molecule. It has a positive region and negative region. Thus, it is easily attracted to some other charged object, like an ion or electron in the air. Hence, fog or rain droplets tend to form around ions of electrons in the air.
