Q 1 : What are negative ions ?
They are oxygen atoms with an extra electron. And they can help you feel better. Technically speaking " ions are charged particles in the air that are formed in nature when enough energy acts upon a molecule such as carbon dioxide, oxygen, water, or nitrogen to eject an electron from the nolecule leaving a positively charged ion. The displaced electron attaches itself to a nearby molecule, which then becomes a negatively charged ion. It is the negative ion of oxygen that effects us the most".
