How is indium tin oxide a n-type semiconductor?
I was reading about indium tin oxide (ITO) and that it is considered a n-type semiconductor. However, that doesn’t make sense to me. If just one In(III) is replaced by Sn(IV) then we would have an ...

Is the charge spread throughout the molecule in polyatomic ions?
The following line was given in a chemistry textbook
"In case of polyatomic ions, the net charge is possessed by an ion as a whole and not by a particular atom."
I understand this in cases ...

How to display atomic charges from MOPAC calculation?
MOPAC (http://openmopac.net/) is nice semiempirical code. It also calculates charges on atoms.
Is there a free GUI to display them please ? What I know, Avogadro diplays vibrations, JMol orbitals......

Why does Lewis dot structure of CO not have formal charges close to 0?
If we draw the Lewis dot structure of CO like this:
The formal charge on each atom must be 0 But in the actual structure, formal charge on carbon is $-1$ and formal charge on oxygen is $1$.
But I ...

Does formal charge or the octet rule take precedence over one another?
In my AP chem test, I had a question that asked me to find the bond order of the ion $\ce{SO3^2-}$.
To draw the lewis structure, I determined that there are a total of $6+3\cdot 6+2=26$ electrons, and ...

What is the significance of charge balancing when analysing system speciation (carbonate system given as an example)?
Following on from my previous question and accepted answer, How do I quantify the carbonate system and its pH speciation?, I also calculated a charge balance ($CB$) on the system where $z$ is the ...

Calculating the net charge of DNA oligo
How can I calculate the net charge of a DNA oligo? I have a bunch of different sized oligos (vary from 9 to 50nt long) which I am using for microscopy (DNA-PAINT) and I need to know their charges ...

Shouldn't the Cl- be placed beside the charged N+ ion when writing the structural formula of Benzenediazonium chloride?
I found the structural formula of Benzenediazonium chloride written on a website:
I believe that the Cl- ion is stabilizing the N+ ion.
So, shouldn't the structural formula be written like the above ...

Forming conjugate acid of borate anion via protonation
I am a biologist so please forgive me as I likely won't be as rigorous as a professional chemist. I am using the RDKit package to extract organic molecules from salts, where one ion is organic and the ...

Can a neutral molecule have nonzero formal charge?
I initially thought that yes, there must be a neutral molecule that exists with a nonzero formal charge on at least one atom.
But thinking more into it, if we are given a neutral molecule where the ...

Charge polarisation in acetamide molecule due to different lithium salts (varying anions)
I am trying to understand how will acetamide molecules behave in the presence of lithium salts with different anions (nitrate, bromide and perchlorate).
Among the three, it is evident that bromide is ...

Why exactly do we need formal charge? [closed]
Formal charge is considered to be the charge present in one atom by considering all the bonds to be 100% covalent.What is the significance of 100% covalent here? Why are we considering the bonds to be ...

Stability of Carbanions
For comparing stability of carbanion, we use the fact that "negative charge is stable on more electronegative atom." So, The stability order is, {electronegative order: $\mathrm{sp \gt sp^2 \...

Does formal charge affect bond polarity?
Bond polarity, as far as I understand, is a measure of the degree to which shared electron density is distorted, and thus solely depends on the electronegativity difference.
Up until now, I had ...
