Verified step by step guidance1
Identify the cation and anion in the ionic compound. The formula given is NH\_4SCN. Here, NH\_4\^+ is the ammonium ion, which is the cation.
Next, determine the anion part of the compound. The SCN\^- ion is called thiocyanate, which is different from cyanide (CN\^-), sulfate (SO\_4\^{2-}), or thiosulfate (S\_2O\_3\^{2-}).
Combine the names of the cation and anion to name the compound. Since the cation is ammonium and the anion is thiocyanate, the compound is named ammonium thiocyanate.
Recall that the name of an ionic compound is always the cation name followed by the anion name without changing the cation name.
Verify that the formula matches the name: NH\_4\^+ (ammonium) and SCN\^- (thiocyanate) combine to form ammonium thiocyanate.
