Bromine can form several different oxides:

• Dibromine monoxide (Br₂O)

• Bromine dioxide (BrO₂)

• Dibromine trioxide (Br₂O₃)

• Dibromine pentoxide (Br₂O₅)

• Tribromine octoxide (Br₃O₈)

Also, a number of ions are bromine oxides:

• Hypobromite (BrO⁻)

• Bromite (BrO₂⁻)

• Bromate (BrO₃⁻)

• Perbromate (BrO₄⁻)

And the bromine monoxide radical:

• Bromine oxide (BrO)
