An ion is an atom [or group of atoms] with either an extra electron or has a deficiency of one. It thus has a positive or negative charge respectively.
e.g. Sodium Chloride (table salt) is a mixture of positive Sodium ions and negative Chlorine ions. The sodium ions are positively charged and chlorine ions are negatively charged, which are thus attracted to each other because of their opposite poles.
e.g. Ammonium nitrate (common salt in fertiliser) NH4NO3 in solid state, which changes in two oppositly charged ions when dissolved in water:
NO3- nitrate ion and NH4+ ammonium ion
An anion is an atom with a negative charge.
H
Because they have gained or lost electrons and are no longer neutral.
Mostly between metals and nonmetals. You donate an ion to another atom.
No. A "broken" atom of gold may be an ion, but it does not have the same chemical properties as an intact atom of gold.
bicarbonate of soda contains the alkali metal sodium, though its alkaline properties are actually due to the bicarbonate ion.
its ion and atom properties differences is atom is like science ion-chemistry
H
Because they have gained or lost electrons and are no longer neutral.
No, as the number of protons and neutrons in each will be different.

The ammonium ion (NH4+) is an ion, and is therefore found in compounds. As such, the state of matter it takes depends upon the properties of the compound it is in.Ammonia (NH3), a compound, is a gas at room temperature.
Yes, it is converted from an element to form a compound, since it will only from an ion by finding some other species that will accept the donor electron.
NH3 forms a complex ion with silver called the diamine silver ion, Ag(NH3)2+ which has different properties from an ordinary silver ion (Ag+) among them being that more of its compounds are water soluble.

Because ions are electrically charged particles that have different chemical properties than their parent atoms. For example, salt is not as dangerous because it contains stable sodium ions, not the reactive sodium atoms of its parent. :)
