molecule
|
formed when two or more atoms bond covalently
|
|
lewis structure
|

|
single covalent bonds
|
|
pi bond
|
formed when parallel orbitals overlap to share electrons
|
|
endothermic
|
reactons occur when a greater amount of energy is required break the existing bonds in the reactants than is released when the new bonds form in the product molecules
|
|
exothermic
|
reactions occur when more energy is released forming new bonds than is required to break bonds in the initial reactants.
