![]() IONs will take or release an electron to become balanced again. If it has more protons than electrons,it is a positive ion. These unbalanced charged ION particles are responsible for electron flow (electricity). If the atom has more electrons than protons, it is a negative ion, or ANION. The atom becomes either a positively or negatively charged particle called an ION. When an atom loses or gains an electron, an imbalance occurs. There are two types of ions electrolytic and gaseous or atmospheric. The term plasma treatment as used herein means a treatment of exposing the surface of a substance to an environment of physical and mechanical (bombardment) actions of the plasma. For example, have you ever noticed how the air is stuffy before a storm and afterwards it is refreshing? This is because lightening produces a high concentration of negative ions, which purifies the air and makes it invigorating. An atom that has one extra electron added is called a negative ion (anion). The plasma consists of charged ions (positive or negative), negatively charged electrons, neutral species, radicals, and excited species. Nature is constantly producing negative ions to combat the pollution in the air. Negative ions in the air attract particles of pollution and give them a negative charge, making them seek electrical “ground”, which causes them to fall harmlessly to the floor. Positive air ions are generally molecules of carbon dioxide that have lost an electron, whereas, a negative air ion is generally a molecule of oxygen that has gained an electron. Generally, positive ions weigh more than negatively charged ions, and mobility values are larger than 0.4-0.8 (cm2/Vs). If there’s just a minus sign, it means the charge is minus 1. The negative charge (fewer protons than electrons) for an anion is shown by a number and minus sign after the formula. An atom or a molecule gives up or receives electrons, forming ions. ![]() Your dentist may also give you a fluoride treatment. A net electrically charged atom or molecule is known as an ion. ![]() Both positive and negative ions exist in the air. Examples of Negative Ions Fluoride is sometimes added to community water supplies. Atom wanting and electron What do you do if you are a sodium (Na) atom You have eleven. Very simply an ion is an atom or molecule that has gained or lost an electron. When you have an extra electron or two, you have a negative charge.
