Electrons in a water molecule?

Post by secret » Fri Aug 18, 2006 2:56 am

Hey

I have a questions.

When a H20 molecule is split - I don't quite understand where the 2 electrons are coming from, is someone able to discuss how we get 2e- from a split water molecule in the process of light reactions. (equation below)

H2O → 2H+ + 2e- + 1/2O2

Thanks

its because during the reaction H becomes a positively charged kation (H+), so it means that H must have lost some an electron. And because, there are 2 hydrogen atoms, each losing an electron => 2 e- are produced... ;)

Hydrogen= one proton(H+) and one electron(e-)

Hydrogen Atom = one proton (H+) and one electron (e-)

Hydrogen = 2 protons (2H+) and two electrons (2e-)

It's because Hydrogen is referred to it's gas form which always occurs in diatomic form (H2)...:mrgreen:
