Hydrogen Bonding
... Ionic Bonding – Electrons are transferred from one atom to another producing a charge on both atoms (ions), in order to keep them together. NaCl Covalent Bonding – Sharing of electrons between atoms resulting in an overlap of their electron orbitals. Diamond Metallic Bonding – Formed when closel ...

... 1. To know that chemical bonds, the forces that hold atoms together (text definition), are the lowering of energy when atoms come together (additional definition). 2. To describe, differentiate, and give examples of ionic, covalent, and metallic bonds. 3. To use Lewis dot symbols for atoms and ions ...

... number of ways and it is therefore literally impossible to catalog all the possible heats of reaction. To get around this problem we define for each substance a standard reaction and tabulate its associated heat of reaction. These reactions and their associated heats of reaction can then be used to ...

... Therefore more electrons are pushed onto the N atom (because of the positive inductive effect of alkyl groups). One might expect using the same trend that tertiary amine would be the strongest amine base but the trend does not hold. The tertiary amines and corresponding ammonium salts are less ...
