Standard 2: Chemical Bonds - 12% of Star Exam
Biological, Chemical, And Physical Properties Of Matter Result From the ability of atoms to form bonds based on electrostatic forces between electrons and protons, and between atoms and molecules. As a basis for understanding this concept:
State Standard:
Atoms combine to form molecules by sharing electrons t form covalent or metallic bonds, or by exchanging electrons to form ionic bonds |
Students Will Be Able To:
Describe and compare various bonding relationships including ionic, covalent, metallic bonding. |
State Standard:
Chemical bonds between atoms in molecules such as H2, CCH4, NH3, H2CCH2, N2 Cl2, and many large biological molecules are covalent. |
Students Will Be Able To:
Give examples of various covalently bonded molecules. |
State Standard:
Salt crystals such as NaCl are repeating patterns of positive and negative ions held together by electrostatic attraction. |
Students Will Be Able To:
Draw models of ionically bonded compounds. |
State Standard:
In a liquid the inter-molecular forces are weaker that in a solid, so that the molecules can move in a random pattern relative to one another |
Students Will Be Able To:
Compare and contrast the intermolecular forces that determine the states of matter |
State Standard:
How to draw Lewis dot structures |
Students Will Be Able To:
Given the electron configuration, draw Lewis dot structures. |

|
State Standard:
How to predict the shape of simple molecules and their polarity from Lewis dot structures |
Students Will Be Able To:
Draw simple molecules and predict polarity and shape. |
State Standard:
How electronegativity and ionization energy relate to bond formation |
Students Will Be Able To:
Determine type of bonding from electronegativity values and ionization energy values. |

|
State Standard:
How to identify solids and liquids held together by Van der Waals forces to volatility and boiling/melting point temperatures. |
Students Will Be Able To:
Describe how hydrogen bonding and Van der Waals forces effect physical properties such as boiling point, melting point, and volatility |
