Silver (Ag) is an element. Silver (Ag^+) is an ion. In neither case is it a formula unit. A formula unit applies to ionic solids, like NaCl, etc.
AgH is the formula for silver hydride.
The chemical formula of silver phosphide ia Ag3P. The ion of silver is Ag+.
The formula for silver carbonate is Ag2CO3
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
NaBr is a formula unit. It represents the simplest, whole-number ratio of ions in an ionic compound, sodium bromide. It does not represent individual molecules but rather the combination of one sodium ion (Na+) and one bromide ion (Br-).
AgH is the formula for silver hydride.
The chemical formula of silver hydroxide is AgOH
The formula unit for silver(III) nitride is Ag3N.
There is only one chloride ion in the formula unit of sodium chloride.
Silver chloride: AgCl
The formula unit of sodium nitrate is NaNO3
The silver ion is Ag+ and the perchlorate ion is ClO4-, so silver perchlorate would have the formula of AgClO4.
There are five hydrogen atoms in one formula unit of the ammonium ion (NH4+).
The chemical formula for silver fluoride is AgF. It consists of one silver ion (Ag+) and one fluoride ion (F-) combined in a 1:1 ratio.
The formula unit of sodium nitride is Na3N. It consists of one sodium ion (Na+) and one nitride ion (N3-).
The chemical formula of silver phosphide ia Ag3P. The ion of silver is Ag+.
The chemical formula AgOH corresponds to silver hydroxide. Silver hydroxide is a chemical compound composed of one silver ion (Ag+) and one hydroxide ion (OH-).
