Assuming it is just a particle of silver with no other interactions, it would just be an atom. It could, in other cases, be an ion instead, however: an ion is nothing more than an atom or molecule that is charged (either positively by losing an electron or negatively by gaining an extra electron.) If the atom/molecule has an equal number of protons and electrons (as it would generally be considered in an ideal textbook situation, assuming no chemical interactions), the net charge is neutral, so it would not be considered an ion.
Bottom line: + charge or - charge is a silver ion, neutral charge is just a plain old silver atom/molecule.
This is a more complicated question than it seems; the answer is "both, and neither." Silver is a metal; its atoms are held together by the "metallic bond". In a sense, any piece of silver, no matter how large, can be regarded as a single molecule with all the atoms participating in the shared metallic bond. However, it's much more common to think of it in terms of single atoms. A single atom of silver is also a molecule of silver.
Pure silver is made of silver atoms. Silver used in everyday life is usually alloyed with other metals such as copper.

what does an atom have in common with an ion?
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
ion
fluoride ion
The number of protons is the same in the atom and the ion of any element.

what does an atom have in common with an ion?
An ion is a positively or negatively charged atom or molecule.
An ion is an atom with a positive or negative charge.
ion
The loss or gain of electrons transform an atom in an ion.
If the number of protons and neutrons are the same, its an atom, if not its an ion
An atom is called an ion if there is a charge on it - positive or negative.
A ion is an electrically charged atom, positive or negative.
When an atom gets charged it is called ion.
atom
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
