Verified step by step guidance1
Identify the compound given: NH4Br. This is an ionic compound composed of ions.
Recall that NH4 is the ammonium ion, which is a positively charged polyatomic ion with the formula NH4^+.
Recognize that Br is the bromide ion, a monatomic ion with a negative charge, written as Br^-.
Since ionic compounds are made of cations (positively charged ions) and anions (negatively charged ions), assign NH4^+ as the cation and Br^- as the anion.
Verify that the charges balance to zero in the compound NH4Br, confirming the correct identification of the ions.
