Covalent Bonds in Complex Covalent Molecules
Some atoms need to share more than one pair of electrons to gain a full outer shell of electrons
If two adjacent atoms share two pairs of electrons, two covalent bonds are formed, also known as a double bond
If two adjacent atoms share three pairs of electrons, three covalent bonds are formed, also known as a triple bond
Nitrogen :
When 2 nitrogen atoms react they share 3 pairs of electrons to form a triple bond
Carbon Dioxide :
