One more, confused
How can you tell by the periodic chart which ions of metals are most easily reduced or oxidized. A website or video would be fine. I know it is quite involved.
thanks again
Oxidation is the loss of electrons so those metals whose electrons are easily lost are oxidized the easiest. Those are the alkali metals (group I) of Li, Na, etc.
Reduction is the gain of electrons. So F2 Cl2 etc gain electrons the easiest. (but those of course are not metals).
To determine which ions of metals are most easily reduced or oxidized using the periodic chart, you can refer to the concept of standard reduction potentials (E°). Standard reduction potentials are a measure of the tendency for an element to gain or lose electrons during a reduction-oxidation reaction.
The greater the positive value of the standard reduction potential, the easier it is for the element to be reduced (gain electrons). The greater the negative value, the easier it is for the element to be oxidized (lose electrons). The standard reduction potentials can be found in reference tables or online resources.
To use these values effectively, you need to compare the reduction potentials of two or more elements. The element with the more positive reduction potential will be readily reduced while the one with the more negative reduction potential will be oxidized.
A useful online resource for finding standard reduction potentials is the NIST Chemistry WebBook (https://webbook.nist.gov/chemistry/). On this website, you can search for specific elements and find their standard electrode potentials.
Additionally, you can refer to the Khan Academy video "Electrochemistry" (https://www.khanacademy.org/science/ap-chemistry/thermodynamics-chemistry/electrochemistry-ap/v/electrochemistry) for a comprehensive explanation of electrochemistry and how to determine the ease of reduction or oxidation.
Remember, the standard reduction potentials help in comparing the ease of reduction or oxidation, but the actual feasibility of a reaction also depends on other factors such as concentration, temperature, and pH.
