The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. When two hydrogen atoms and an oxygen atom get close ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent ... protons within an atom. This is what keeps the atom together. Electrons are attracted to the protons of other atoms ...

Ionization breaks the hydrogen atom down ... to the anode, oxygen is fed to the cathode, where a catalyst creates oxygen ions. The arriving hydrogen protons and electrons bond with these oxygen ...

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two hydrogen atoms ... Nitrogen atoms can form three covalent bonds, so a triple bond forms between ...
