Choose the lewis structure for the hypobromite ion, bro−. choose the lewis structure for the hypobromite ion, . the [br-o]^- ion with three lone-pairs of electrons on the bromine atom, and three on the oxygen atom the [br-o]^- ion with no lone pairs of electrons shown on either the bromine nor the oxygen atom. the ion {^-}br-o, showing a formal charge of -1 on the bromine atom and three lone-pairs of electrons on both the bromine and the oxygen atoms. the [br-o]^- ion with three lone-pairs of electrons on the bromine atom, and one on the oxygen atom. the ion {^-}br-o, showing a formal charge of -1 on the bromine atom and no lone pairs of electrons on either the bromine nor the oxygen atom.

Hypobromite Ion is as follow,
                                           
                                           BrO⁻

For Lewis structure, first add all the valence electrons of elements.
So,
                                Br  =  7
                                 O  =  6 
                                    ------------
                            Total  =  13
As there is one negative charge, add 1 electron in total valence electrons,
So,
                                  13
                                +  1
                              ----------
                                  14
Now, write both elements and make a single bond between them, and subtract 2 electrons for that single Bond.

                                  Br-O

We are now left with 12 electrons,

Start putting these 12 electrons on both elements so that each get 3 lone pair of electrons with complete octet,

The Final Lewis structure is as follow,

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

The disturbance is only parallel to the motion of the wave.
