an ion is basically a charged atom or group of atoms
An ion is any atom that has a positive or a negative charge. A positively charged ion will seek a negatively charged one to unite with, have a glorious 'coupling' and then turn into something totally new and available.
So why do we rave on so much about negative ions? Because the result of every move you move (a net spending of energy) is a positively charged body. The molecules in your body are left holding a positive charge. They are unavailable for future 'couplings' unless we get a new batch of attractive and giving negative ions in quickly.
As we hear so often these days, things ain't what they used to be. The air is different. Putting it very frankly and unscientifically, it's full of crud. Positively charged crud. Nothing ever 'goes away' on our little green planet and every exhaust, every chimney plume, every cowfart, stays within our thin and fragile ionosphere. It stays in the air we gulp as we run along the beach, it stays in the water we drink, and it stays in the food we eat. And all of it this pollution is useless for energy production within the body.
If an atom gains an electron (or electrons) in its outer shell, it has net negative charge, and becomes a negative ion.
A negative ion is called an anion. (A positive ion is a cation.)
If an atom takes one or more electrons as a result negative ion is formed. The reason is that an electron is negatively charged and normally an atom is neutral. if it takes electrons then negative ion is formed which is more likely to give that electron.
An example of a negatively charged ion is an anion. Anions are formed when an atom gains electrons, resulting in an overall negative charge.
A negatively charged atom is called an anion, which is an atom that has more electrons than protons.
an atom with one or more extra electron(s) in its valence band. There are also molecular ions but they are more complicated to explain than simple atomic ions.
An atom that has become charged is called an ion. It can be positively charged (cation) if it has lost electrons, or negatively charged (anion) if it has gained electrons.
A negatively charged atom of chlorine is called a chloride ion.
When naming an ionic compound, the name of the cation (metal or positively charged ion) goes first, followed by the name of the anion (nonmetal or negatively charged ion).
When an atom gains an electron, it becomes negatively charged and forms an anion. This process is known as reduction, and it can change the chemical properties of the atom by affecting its reactivity and ability to form bonds.
An electrically charged atom or molecule is called an ion. An ion can be either positively charged (cation) or negatively charged (anion), depending on the number of electrons it has relative to its number of protons.
