Is silver an atom or ion?
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...
Asked in Oxidation Numbers
What is the oxidation number of silver ion?
+1 . The oxidation number of an ion is always equal to the charge. The silver ion is Ag+ in compounds such as silver chloride. There is also an Ag3+ in compounds such as AgO, which contains Ag+ and Ag3+ in 1:1 proportions, so contains silver with +1 and +3 oxidation numbers and is called silver(I,III) oxide ...
