Answer 1

The bromate ion, BrO₃⁻, has a central bromine atom double-bonded to one oxygen and single-bonded to two other oxygens, with the entire ion carrying a negative charge.

Step-by-step explanation:

The correct answer is option B, D, and E. In the Lewis structure for BrO₃⁻ (bromate ion), the bromine atom is central and forms bonds with three oxygen atoms. One of the oxygen atoms is double-bonded to the bromine with two lone pairs, and the remaining two oxygen atoms are single-bonded, each with three lone pairs.

The bromate ion carries a negative charge, which is indicated by putting the entire structure in brackets with a superscript negative sign. This arrangement forms a trigonal planar structure around the bromine atom, consistent with its sp² hybridization.
