Ionic/Covalent Bonding Concept

No Evidence

No Evidence
Developing

The student can sometimes determine the electronegativity difference but does not yet understand the relationship of this calculation to attractive forces within a bond and using it to determine the bond type.
Sufficient

The student can determine electronegativity difference 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.
Proficient

The student knows how atoms from ionic and covalent bonds and can use electronegativity calculations to explain the type of bond.
Exemplary

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

No Evidence

No Evidence
Developing

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

The student can name some ionic and covalent bonds but needs more practice with polyatomic naming.
Proficient

Student can name ionic compounds containing main group or transition metals, covalent compounds, and polyatomic ions.
Exemplary

Student can name ionic compounds containing main group or transition metals, covalent compounds, and polyatomic ions without any errors.
Writing Ionic/Covalent Formulas

No Evidence

No Evidence
Developing

The student can write the names of binary ionic bonds but struggles with naming all other types of bonds.
Sufficient

The student can write names for ionic and covalent bonds but struggles with polyatomic ions.
Proficient

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

Student can write the chemical formulas of common polyatomic ions, ionic compounds (main/transition) and covalent compounds without any errors.
Electron (Lewis) Dot Structures

No Evidence

No Evidence
Developing

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

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.
Proficient

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

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