Ionic/Covalent Bonding Concept

Not Yet

The student can sometimes determine percent ionic character, but does not yet understand the relationship of this calculation to attractive forces within a bond.
Progressing

The student can determine percent ionic character, and can sometimes connect this calculation to the determination of an ionic or covalent bond. More understanding of the attractive forces within a bond is needed.
Meets Expectations

The student knows how atoms from ionic and covalent bonds, and can use percent ionic character calculations to explain the type of bond.
Exceeds Expectations

The student can easily differentiate between and ionic/covalent bond by looking at location of bonding elements on periodic table & can teach the conceptual differences to others.
Naming Ionic/Covalent Compounds

Not Yet

The student can name binary ionic bonds, but struggles with all other types of bond names.
Progressing

The student can name ionic and covalent bonds, but needs more practice with acid naming.
Meets Expectations

Student can name ionic compounds containing main group or transition metals, covalent compounds, acids, and bases, using (IUPAC) nomenclature rules.
Exceeds Expectations

Student creates a poem/skit/song/or other product that provides a template for naming all types of bonds - ionic, covalent, acids, bases.
Writing Ionic/Covalent Formulas

Not Yet

The student can write the names of binary ionic bonds, but struggles with naming polyvalent metals in bonding and all other types of bonds.
Progressing

The student can write names for ionic and covalent bonds, but struggles with polyvalent metals and acid names.
Meets Expectations

Student can write the chemical formulas of common polyatomic ions, ionic compounds (main/transition) covalent compounds, acids, and bases.
Exceeds Expectations

Student creates a template that provides a flowchart/pathway for naming all types of bonds - ionic, covalent, acids, bases, including both classic names and stock system names for both ionic & covalent bonds.
Electron Dot Structures

Not Yet

The student can draw a basic electron dot structure for one element, but struggles with bonded elements.
Progressing

The student can draw electron dot structures for 2 bonded elements, but struggles with determining how many atoms of each element are needed to complete the bond.
Meets Expectations

Student can construct electron dot formulas to illustrate ionic & covalent bonding.
Exceeds Expectations

Student teaches others how to draw electron dot formulas and explains the difference in ionic & covalent bonding.
