How many double bonds are there in the most significant resonance structure of the bromate ion BrO3 )?
So, the final lewis structure of BrO3- contains two double bonds and one single bond, each oxygen atom has 8 valence electrons, and the bromine central atom has 12 valence electrons in its outermost shell as it has the ability to expand octet.
What is the formal charge on the bromine atom in this Lewis structure of the bromate ion bromate?
The Bromine has a formal charge of 0, and this is still -1. That makes sense: the total charge–formal charge here is -1 and that matches with the -1 here. One last thing we need to do: this is a negative ion, the BrO3- ion–Bromate ion.
What is the shape of nh4+?
tetrahedral
That leaves a total of 8 electrons in the outer level of the nitrogen. There are therefore 4 pairs, all of which are bonding because of the four hydrogens. The ammonium ion has exactly the same shape as methane, because it has exactly the same electronic arrangement. NH4+ is tetrahedral.
Can Xe have an expanded octet?
Xe does not follow the octet rule. It actually bonds. It will hold more than 8 electrons. Xenon having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons.
Is BrO3 planar molecule?
Neutral BrO3 as written does not exist, at least not for long. (It would require some kind of high energy radical) The bromate ion, BrO3- has a trigonal pyramidal geometry.

How many resonance structures does so4 2 have?
six
The six main resonance structures of the sulfate ion, SO42−.
How do you find the formal charge of a Lewis structure?
To find formal charges in a Lewis structure, for each atom, you should count how many electrons it “owns”. Count all of its lone pair electrons, and half of its bonding electrons. The difference between the atom’s number of valence electrons and the number it owns is the formal charge.
What is the shape of no3?
trigonal planar
In nitrate, there is one central atom which is surrounded by three identically-bonded oxygen atoms which lie at the corners of a triangle and at the same one-dimensional plane. In essence, nitrate has 3 electron domains and no lone pairs. Therefore, NO3– molecular geometry is slightly bent and is trigonal planar.
What is the structure of base bromate?
Bromate is a bromine oxoanion and a monovalent inorganic anion. It is a conjugate base of a bromic acid. Bromates, inorganic, n.o.s. is a colorless to light colored solid. Slightly soluble in water and denser than water. Contact may cause irritation to skin, eyes, and mucous membranes.
What is the Lewis structure of BrO3-?
So, the final lewis structure of BrO3- contains two double bonds and one single bond, each oxygen atom has 8 valence electrons, and the bromine central atom has 12 valence electrons in its outermost shell as it has the ability to expand octet.
What is the mechanism of exposure to bromate?
Exposure of mammalian cells to bromate (BrO3-) generates oxidative DNA modifications, in particular 7,8-dihydro-8-oxo-guanine (8-oxoG). The damaging mechanism is quite unique, since glutathione, which is protective against most oxidants and alkylating agents, mediates a metabolic activation, while bromate itself does not react directly with DNA.
What is the name of the compound with the formula bromate?
Bromate is a bromine oxoanion and a monovalent inorganic anion. It is a conjugate base of a bromic acid. Bromates, inorganic, n.o.s. is a colorless to light colored solid. Slightly soluble in water and denser than water.
