Detailed Solution

The above statement is True.
The rate of electron flow per unit time is known as electric current. Free electrons or ions are necessary for the conduction of current. A substance's conductivity rises as its ion concentration does. The amount of free electrons in metals is quite substantial. Metals are therefore effective electrical conductors. The movement of ions, which are both positive and negative charge-carriers, causes electric conduction in gases. A variety of neutral or inert gases make up air. As a result, it has little to no charged particles or free ions that could conduct electricity. Air therefore has poor electrical conductivity. Electricity does not conduct well through air. Only when there is moisture in the air or a very high pressure level can air conduct electricity.
