UV-Visible Spectroscopy in the analysis of sodium chloride in potato chips
Here is the question and answer out of an exam paper:
Firstly, I thought UV-Visible can also use radiation in the visible spectrum. Also when analyzing sodium chloride (a molecule), then UV-Visible ...

Is the valence band neutral?
While studying about band theory of semiconductors, I observed that when the electrons were excited from the valence band to the conduction band, they left behind holes in the valence band. From my ...

Photoelectric effect and electron loss
I've read that when a certain amount of UV light is shone on a metal surface, electrons are ejected (the photoelectric effect).
Are these electrons from the metal atoms themselves? and in case they ...

Where do the electrons not in the S1 orbital get this "extra energy" from?
In this video, Sal Khan says that an electron reaches a higher energy state if the electron possesses more energy. So I assume that, say in the case of carbon, the electrons not in the S1 orbital have ...

Intuition for electrode potential
If I connect a zinc half cell (Left hand side) and a copper half cell (right hand side), I get an E cell value of 1.1V taken from the voltmeter. If I replace the voltmeter with a light bulb, I will ...
