Oxygen has 8 plus-charged protons. The number of minus-charged electrons is______.

Respuesta :

I've always been told that it's eight. This is only because the atom has to have the saem protons (positively charged) neutrons and electrons (negatively charged). However this does not occur with all atoms. :)
Every atoms which are not charged must have equal number of protons & electrons.

In short, Your Answer would be 8
