Chemical Bonds Quiz
California Standards
Chemistry 1d. Students know how to use the periodic table to determine the number of electrons available for
bonding
Chemistry 2 a. Students know atoms combine to form molecules by sharing electrons to form covalent or metallic
bonds or by exchanging electrons to form ionic bonds
Chemistry 2b. Students know chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2, N2, Cl2,
and many large biological molecules are covalent.
Chemistry 2c. Students know salt crystals, such as NaCl are repeating patterns of positive and negative ions held
together by electrostatic attraction.
