Ionic bond
Attractions between cations and anions
Cation
Positive ion
Anion
Negation ion
Covalent bond
Equal amount of electrons are donated by each atom to share pairs of electrons
Nonpolar covalent bond
An equal sharing due to an equal pull
Polar covalent bond
Unequal sharing due to an unequal pull
Hydrogen bond
A weak charge between slightly positive and negative charges
Decomposition reaction (Catabolism)
Breaks chemical bonds via hydrolysis reaction
Synthesis reaction (Anabolism)
Forms bonds via dehydration synthesis reaction (condensation)
Exchange reaction
Involves decomposition first, the synthesis
Reversible reaction
Seek equilibrium by balancing opposing reaction rates
