Which of the following choices best describes how electrons are transferred from one object to another?
there are extra electrons in the air that are transferred from one object to another
electrons are transferred when objects come into direct contact with each other
electrons are transferred when one object creates electrons and another object destroys them.
electrons are not transferred between objects

Option (b) is the correct answer.

Explanation:

When two atoms or substances come in contact with each other then they react with one another. As a result, there will be exchange of electrons between them.

For example, when sodium comes in contact with chlorine then it results in the formation of sodium chloride.

Thus, we can conclude that out of the given options, electrons are transferred when objects come into direct contact with each other.
