## What is the structure of BrO3 minus?

The overall formal charge in BrO3- is -1. Total 16 lone pairs electrons and 10 bonded pairs electrons present in BrO3- lewis structure. The molecular geometry of BrO3- is trigonal pyramidal and electron geometry is tetrahedral.

## What is the molecular geometry of BrO3?

(It would require some kind of high energy radical) The bromate ion, BrO3- has a trigonal pyramidal geometry.

**Does BrO3 have an expanded octet?**

Transcript: This is the BrO3- Lewis structure. Bromine has 7 valence electrons. Oxygen has 6, and we have 3 Oxygens, and then we need to add this extra valence electron here for a total of 26 valence electrons for BrO3-. It can have an expanded octet, meaning it can have more than 8 valence electrons.

**How do you determine resonance structures?**

Using Formal Charges to Identify viable Resonance Structures

- The greater the number of covalent bonds, the greater the stability since more atoms will have complete octets.
- The structure with the least number of formal charges is more stable.
- The structure with the least separation of formal charge is more stable.

### How many resonance structures does sulfur dioxide have?

two resonance structures

Hint: Sulfur dioxide ($S{{O}_{2}}$) has two resonance structures which contribute equally to the overall hybrid structure of the molecule.

### What is the oxidation number of BrO3?

Definitely this number is +5. This +5 is the oxidation number of Bromine in Bromate.

**What is the Iupac name of BrO3?**

bromateBromate / IUPAC ID

**What BrO3 1?**

Bromate is a bromine oxoanion and a monovalent inorganic anion. It is a conjugate base of a bromic acid. ChEBI.

## Which resonance structure is the best?

Remember, the best resonance structure is the one with the least formal charge. This is why formal charges are very important. Atoms that are missing one or more electrons will have a positive charge. An atom with many electrons will have a negative charge.
