How does SOFC work?
The Solid Oxide Fuel Cell is a particular case in which an oxide is used as a conductor. Once i've heard that oxides usually aren't good conductors but it turned out that a lot of oxides are ...

Electron configuration and the 2p orbital
I looked through the questions already asked about this topic and they were very specific and over my head. I'm having trouble with the basics.
When drawing orbital diagrams I know electrons are ...

Experimental Validation of Schrodinger's Electron Cloud theory
I am currently doing a report for school on the electron cloud atomic structure theory. One of the major points on my report is the experiments performed by the scientists (Schrodinger and Heisenberg) ...

How much energy is required to make an ion?
So say that I have a normal hydrogen atom (not an isotope, just regular normal hydrogen atom) and I want to make it into an ion $\text{H}^+$. Since to make an ion of that formula I need to take away ...

Reduction by thermionic electrons
Certain reduction reactions require electrons as reducing agents. Is the overlapping of orbitals is necessary for electron transfer? I mean if a element $\ce{X}$ is heated and it gives out thermionic ...

In VSEPR, why do lone pairs have stronger repulsion?
I've seen conflicting answers:
Lone pairs take up more space because there isn't another atom on the
other end. With a greater volume to move around in, they can repel
more.
Lone pairs are closer to ...

Degradation via electrolysis and electrode surface area
What is the relationship between electrode surface area and processes such as electrolysis/electrode polarization?
Let's say for example I want a fixed electric field between two electrodes in a ...

The existence of a principal quantum level or energy shell after the loss of an electron from the outer shell of an atom
With the loss of an electron from $\ce{Li}$ ($\mathrm{1s^2\ 2s^1}$), we get $\ce{Li+}$ ($\mathrm{1s^2}$), then the 2nd shell where the electron had been revolving in $\ce{Li}$ will get disappeared or ...

Can someone elaborate what it means when its said that electron shells do not exist in multi electron systems?
I'm an undergraduate student in chemistry. I'm trying to grapple with all the new stuff we're learning and making sense of it. Now I want to know if electron shells really "exist" in multi ...

The first electron affinity of an atom
I've read that the first electron affinity is always negative, meaning that energy is always released upon the addition of this first electron. However, I don't think this will apply to noble gases. ...

Terms used to describe the Pauli exclusion principle
This is a very simple question. Today, someone explained to me that the Pauli exclusion principle says that "no two electrons can occupy the same energy state". However, I believe that this ...

What is the net gain of charge carriers in a semiconductor if an atom is removed?
In pure germanium, all Ge atoms are bonded with a tetrahedral geometry. It has a band gap and is a semiconductor. If we remove one Ge atom, what type(s) and how many charge carriers will be generated? ...

Why is polystyrene (PS) an electrical insulator
The reason behind why graphite is electrically conductive is as ancient as the age of the Queen: that, electrons inside the benzene ring are delocalised.
However, if one looks the repeating unit of ...

Is the spin of the transferred 4s electron always opposite to the spin of 3d electron in chromium?
I am studying atomic structure and found out that Chromium has an exception in electronic configuration. One electron from 4s jumps to 3d to achieve stability.
let's say the spin of transferred ...
