:::O-Cl::=O::
So formal charge of first oxygen is (6 ve-6 dots-1 line)=-1
Chlorine (7 ve-4 dots-3 lines)=0
second oxygen (6 ve-4dots-2 lines)=0
so total charge -1+0+0=-1

To draw the Lewis structure for ClO3(-1), first place the Cl atom in the center, then attach three O atoms around it. Add one extra electron to represent the -1 charge. Make sure each O atom has a complete octet and that the Cl atom has a formal charge of 0.

∙ 6y agoThere will be a total of 26 electrons. Put Cl in the middle with 3 O's around it. Place 3 lone pairs around each O and 1 lone pair on the central Cl. This is the Lewis structure.

Is PH3 a Lewis acid or base?
It is a lewis base because of its lone pair of electrons that can be "donated". If you draw/look at the lewis structure it is much easier to tell. Especially when the formula is not that of an ion!
What is the Lewis structure for calcium nitride?
The Lewis structure for calcium nitride (Ca3N2) consists of one calcium atom with two nitrogen atoms bonded to it. The calcium atom donates two electrons to each nitrogen atom, forming ionic bonds. The calcium atom has a 2+ charge, while each nitrogen atom has a 3- charge.
A possible Lewis structure of a molecule for which more than one Lewis structure can be written is called?
Resonance structure.
Draw the Lewis structure for Li?
The Lewis structure for lithium (Li) consists of the symbol "Li" with a dot representing its valence electron. Since lithium has only one valence electron, it is shown as a single dot around the "Li" symbol.
What is the Lewis dot structure for germanium?
The Lewis dot structure for germanium (Ge) is: Ge: :Ge:
Draw the Lewis structure for tert-butyl?
The Lewis structure for tert-butyl (tert-butyl group) is a carbon atom (central atom) bonded to three other carbon atoms and one hydrogen atom. The central carbon has a total of four single bonds, satisfying its octet. The three carbon atoms are each bonded to the central carbon, and a hydrogen atom is bonded to one of the three carbon atoms.
Draw Lewis structure for HClO?
The Lewis structure for HClO consists of one hydrogen atom bonded to one chlorine atom and one oxygen atom. The chlorine atom has two lone pairs of electrons and the oxygen atom has one lone pair. The oxygen atom is double bonded to the chlorine atom.
How do you draw the Lewis structure for h2s2?
To draw the Lewis structure for H2S2 (disulfur dihydride), start by calculating the total number of valence electrons: 2 from each hydrogen and 6 from each sulfur, for a total of 16 electrons. Connect the two sulfur atoms with a double bond, then add hydrogen atoms to each sulfur to satisfy the octet rule. Distribute the remaining electrons to satisfy the octet rule for each atom, with each sulfur having a lone pair.
What do you use to draw a Lewis structure of either molecule or atom?
dots
How do you draw the Lewis structure for an acetate ion?
To draw the Lewis structure for the acetate ion (CH3COO-), first determine the total number of valence electrons (32). Then place the atoms in a way that minimizes formal charges, with the carbon atom in the center bonded to two oxygen atoms. The oxygen atoms should each have a -1 charge to fulfill the octet rule. The final structure will have a double bond between the central carbon atom and one of the oxygen atoms.
What is the first thing you should do if you want to determine if a molecule is polar or not?

What does the Lewis dot structure for sodium look like?
Will this link help you?, it is quite impossible to draw a Lewis dot structure in this simple text editor. See related links.
What is the Lewis structure of ethanol?
The Lewis structure of ethanol (C2H5OH) shows a central carbon atom with three hydrogen atoms attached and a hydroxyl (-OH) group. The carbon atom forms single bonds with the hydrogen atoms and the oxygen atom of the hydroxyl group. The oxygen atom in the hydroxyl group has two lone pairs of electrons.
Draw the two geometrical isomers of chloroaquotetrammine cobalt 2 chloride?
Chloroaquotetrammine cobalt(II) chloride has two geometrical isomers: cis isomer and trans isomer. In the cis isomer, the chloride and ammonia ligands are adjacent to each other, while in the trans isomer, they are opposite to each other. This results in different spatial arrangements of ligands around the central cobalt ion.
Is PH3 a Lewis acid or base?
It is a lewis base because of its lone pair of electrons that can be "donated". If you draw/look at the lewis structure it is much easier to tell. Especially when the formula is not that of an ion!
