or - how chemistry and electricity are related Electrochemistry or - how chemistry and electricity are related

What makes chemistry happen? The electrons in atoms determine chemical behavior But, not all the electrons Valence

Build an oxygen atom

Why it is H2O and not H4O

Electrons form chemical bonds Shared electrons make covalent bonds Transferred electrons make ionic bonds It’s really not either/or - all bonds are more or less ionic or covalent The bond character depends on how close each of the participant atoms is close to a full shell - 8 valence electrons
