movement of electrons

[ali_boutrosdisc3H]

does the passing of electrons come from the atoms themselves or from the bonds they create?

[Alexandra_Shambayate_2L]

It depends on the mechanism, but it can come from either. Sometimes the electrons come from the atoms themselves, such as in the example of O- or Br- giving an e- to C+; other times it comes from the bonds, such as from a single, double or triple bond giving an e- to an atom.

[Juanalv326]

You can either have the subsititution or addition reaction where one reactant is substituted for another compared to addition where one is broken off than the other is added once a certain reactant left
