Learning Scale: Unit 4 – Chemical Bonds
< Level 2-Emerging:
Achieving less than a Level 2.0 indicates a deficiency mastering one or more of the level 2
learning targets. These deficiencies must be corrected and learning demonstrated prior
to beginning work on Level 2-4. To meet that goal I should:
 Review Level 2 Learning Targets with my teacher.
 Search for instructional videos on YouTube that can help me better understand the
ideas on this learning scale sheet.
 Come in during tutorial to get one-on-one help from my teacher
 After learning the material, I need to talk to my teacher about how I will
demonstrate my learning.

I can predict the relative electronegativity of any two elements on the periodic
table.
I can identify the number of valence electrons in a neutral atom and explain why
these electrons are important in chemical bonding.
I can predict whether an atom will gain or lose electrons when bonding using: its
location on the periodic table, its oxidation number(s), a Lewis Dot Structure,
and/or its relative electronegativity value.
I can predict the formation of anions and cations, and the relative strength of
charges.
I can predict the type of bond (ionic, polar covalent, non-polar covalent, metallic)
that will form between two atoms if I know the relative electronegativity difference
between them.
I can describe what is happening at the molecular level when ionic compounds or
covalent molecules are created, as well as the types atoms that typically create
those types of bonds.
I can define intermolecular forces as the force of attraction that is between
separate molecules.

I can draw Lewis Dot Structures of simple ionic compounds and covalent molecules.
I can model what is happening at the molecular level when a chemical bond is
formed (ionic, polar covalent, non-polar covalent, and metallic bonds).
I can name and write the formulae of simple covalent molecules.
I can name and write the formulae of ionic compounds containing metals with one
ionic charge.
I can name, write the formulae, and state the charge of polyatomic ions with the
assistance of a chart.
I can summarize what is happening at the molecular level between intermolecular
forces, and use this understanding to explain the relative melting and boiling points
of ionic compounds, polar covalent molecules, non-polar covalent molecules, and
metallic compounds.

I can classify different intermolecular forces (London dispersion, dipole-dipole
interaction, & hydrogen bonds) by strength of attraction.
I can name, write the formulae, and state the charge of polyatomic ions with the
assistance of a chart (specifically carbonates, sulfates, nitrates, phosphates,
hydroxide, & ammonium).
I can name and write the formulae of ionic compounds containing metals with
multiple ionic charges.
I can model what happens to conductivity when ionic compounds are dissolved in
water.
I can write, name the formulae, and diagram the Lewis Dot Structures complex
covalent bonds (including acids?)
