Sugden
Above all, his name is Sugden, not Sudgen.
What he said
He did not say that the octet rule is never violated.
On the contrary, he suggested that "the maximum number of electrons in the valency orbit can not [sic] exceed eight". (source)
This means, while he denies that the octet rule ...

When I was new on the stack exchange( now i consider myself an old member(1 month)),the problem i faced was most of my questions were marked as duplicate of other questions.
I can't understand that why people mark some questions as duplicate,there are several possibilities,,maybe the person who h...

From what I was taught in middle school, cations are those ions that move towards the cathode, likewise anions are those ions which move towards the anode.
I didn't have issues with this back then, since all we studied were electrolytic cells. But now that we've crossed over to electrochemical c...
An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or facilitating chemical reactions through the introduction of electrical energy. A common example of an electrochemical cell is a standard 1.5-volt cell meant for consumer use. This type of device is known as a single Galvanic cell. A battery consists of two or more cells, connected in either parallel or series pattern.
== Half-cells ==
An electrochemical cell consists of two half-cells. Each half-cell consists of an electrode and an electrolyte. The two half-cells may use the same...
An electrolytic cell is an electrochemical cell that undergoes a redox reaction when electrical energy is applied. It is most often used to decompose chemical compounds, in a process called electrolysis—the Greek word lysis means to break up. When electrical energy is added to the system, the chemical energy is increased. Similarly to a galvanic cell, electrolytic cells usually consist of two half cells.
Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and bauxite into aluminium and other chemicals. Electroplating (e.g. of copper, silver, nickel or chromium...
The values of standard electrode potentials are given in the table below in volts relative to the standard hydrogen electrode and are for the following conditions:
A temperature of 298.15 K (25 °C);
An effective concentration of 1 mol/L for each aqueous species or a species in a mercury amalgam;
A partial pressure of 101.325 kPa (absolute) (1 atm, 1.01325 bar) for each gaseous reagent. This pressure is used because most literature data are still given for this value rather than for the current standard of 100 kPa.
An activity of unity for each pure solid, pure liquid, or for water (solvent)....
