Ionization can affect the atom nucleous?
I remember when in scool my science teacher told me that electrical reactions, such as ionization, and chemical reactions does not have any effect on the nucleous?
I do not read enogh to have an anwer to this question. If the charge of an electron is equal to the charge of a proton but with different polarity, why it does not create any effect on the nucleous?
Readings on cold fusion topic make me think my teacher was wrong and there is a little effect on the nucleous caused by chemical processes such as electrolysis.
