Hallo, Jeong Mo Lee!

The charge transfer in chemistry can be mediated by cations (e. g. protons) and anions as well. In physics there are many charged elementary particles.

Best wishes

When it comes to electron transfer process both the terms electron transfer and charge transfer are used interchangeably. As you have said, indeed electron transfer leads to charge transfer. You can have a look at the previous discussion

Whenever the charge is transferred there is no evidence of weight gain or lose and no evidence of electrons movement in electronics device and wire conducting .

Charge Transfer is same as electron transport.

The difference is Charge transfer is usually associated with charge transfer complexes formed between donor and acceptor moieties, occurs through photon absorption -

D+ A+ photon ⟶D+ A− (colored complexes)

In electron transfer no photon is needed (Marcus theory)

D+A and D+A-

Charge transfer and electron transfer are same. In both the cases the final product are same. In fact anions and cations both have different charge that are involved in the reaction process. But there charges are also due to change in the number of electrons.

Charge transport is the same as electron transport. There is is difference between electron transfer and charge transfer. ... In electron transfer no photon is needed and the process follows Marcus theory whereby a barrier is crossed between and D X + + A X − , i.e. this is a thermal process with an activation barrie

Charge transfer: a) You can transfer electrons b) in conductive liquids you can move also positive charges (positive Ions) c) in doped semiconductors you can move "holes" (so lack of electrons) in the opposite direction of the electron move

Is electron transfer is a ground state phenomenon? Can any body explain what is the difference between ET and PET (photo induced electron transfer) ?

Strictly speaking, charge transfer refers equally to positive and negative charge displacements if no additional specifications are provided. Besides, negative charge teansfer doesn't necessarily mean the involvement of electrons since the process can be achieved via negatively charged ion species.

It clearly turns out, following the comments of several colleagues like Behnam Farid and Alberto Moro, that charge transfer is a more general process (concept) than electron transfer. In addition to several examples they have cited in chemistry and semiconductors physics, one can think of virtual vector bosons exchanged in electroweak interactions where both negative, positive and neutral currents are involved...

Which means the electrical charge transferred between atoms or molecules is measured by an integer number of electrons !!!

Charge may be transferred by electrons (holes), ions, polarons and other charge carriers. So electron transfer is only one way of charge transfer.
