A chemical bond is the connection of different elements through the sharing, transferring or pooling of electrons.
Concept #1: Explanation for Bond Formation
Concept #2: Understanding an Ionic Bond
An ionic bond involves the transferring of an electron from one element to another element.
Concept #3: Understanding a Covalent Bond
A covalent bond involves the sharing of electron(s) between elements.
Concept #4: Understanding a Metallic Bond
A metallic "bond" isn't really a bond. Think of electrons as being loosely connected or "pooling" on the surface of many metals.
Depending on the element or elements involved we can describe bonds as forming: atomic elements, molecular elements, molecular compounds or ionic compounds.
Practice: Describe each of the following as either a(n): atomic element, molecular element, molecular compound or ionic compound.
Concept #5: Understanding the Ionic Bonding Model
An ionic bond forms when a cation and anion combine because of their opposite charges.
Practice: Determine the molecular formula of the compound formed from each of the following ions.
a. K+ & P3-
b. Sn4+ & O2-
c. Al3+ & CO32-
