Conservation of electrons/protons

Postby Ada Chung 1C » Mon Oct 07, 2019 7:13 pm

I know that mass and atoms are conserved in a chemical reaction but I'm wondering if electrons or protons are conserved.

I believe that there is charge conservation in chemical reactions; therefore, electrons and protons would be conserved throughout a chemical reaction because the atoms on each side of the equation are balanced.

Does the charge conservation work for ions too?

Electrons and protons have mass as well so based off of the law of conservation of mass, the number of electrons and protons must stay the same in a chemical equation. That's just one way to think about it, because there's also charge conservation as well.

As both electrons and protons have a mass, they are conserved due to the law of conservation of mass. They also need to keep a familiar ratio as to cancel out and cause the atom to be neutral.

I, too, had this question. Can anybody elaborate? I saw an example with an ion and I was confused.

If the molecule has a certain coefficient after balancing the equation, would the electrons also be multiplied by that coefficient?
