sorry, the full question copied and pasted is;
Calculate the valence of bromine and nitrogen in the following compounds. In each case, is bromine or nitrogen a cation or an anion?
• Sodium Bromide (NaBr)
Na+ Br- (Bromine -1 anion)• Bromine chloride (BrCl)
Br+ Cl- (Bromine +1 cation)• Hypobromous acid (HOBr)
H+ O-2 Br+ (Bromine +1 cation)• Sodium bromate (NaBrO3)
Na+ Br+5 O3-6 (Bromine +5 cation)• Ammonium chloride (NH4Cl)
N-3 H4+4 Cl- (Nitrogen -3 anion)• Nitrogen gas (N2)
non-ionized Gas• Sodium nitrite (NaNO2)
Na+ N+3 O2-4 (Nitrogen +3 cation)• Nitric Acid (HNO3)
H+ N+5 O3-6 (Nitrogen +5 cation)those in bold above are my answers.
below are the answers I've been given to check my results
• Sodium Bromide (NaBr)
Bromine -1 anion• Bromine chloride (BrCl)
Bromine +1 cation• Hypobromous acid (HOBr)
Bromine +1 complex anion• Sodium bromate (NaBrO3)
Bromine +5 complex anion• Ammonium chloride (NH4Cl)
Nitrogen -3 cation• Nitrogen gas (N2)
non-ionized Gas• Sodium nitrite (NaNO2)
Nitrogen +3 complex anion• Nitric Acid (HNO3)
Nitrogen +5 complex anionI'm embarrassed to say I'm a little confused
