Below are sample questions representative of the exercises included on this worksheet and related 11.137 Patterns Across the Periodic Table and Reactions skill assessments:

Problem 1Difficulty: Mastery

Use the accompanying integrated evidence table for elements A-D. Which prediction is fully consistent with the data?

AElement A forms ACl2 and is least reactive with water.

BElement C forms C2O and conducts as a metal in solid molecular form.

CElement D forms D+ and a basic oxide with water.

DElement B forms BCl2 and can displace hydrogen from acid.

Solution & Explanation:Element B has two valence electrons, low-to-moderate ionization energy, and reacts with acid, consistent with a +2 metal forming BCl2 and displacing hydrogen.

Problem 2Difficulty: Mastery

A student mixes Na2CO3(aq) with CaCl2(aq) and observes a cloudy solid. Which reasoning best explains the result?

ANa+ and Cl- form insoluble NaCl, while calcium and carbonate are spectators.

BCarbonate ions turn into chlorine atoms because calcium is reactive.

CCa2+ and CO3²- form insoluble CaCO3, while Na+ and Cl- remain dissolved.

DNo reaction occurs because all carbonate salts are soluble.

Solution & Explanation:Most group 1 salts are soluble, but many alkaline earth carbonates are insoluble. Calcium carbonate forms the cloudy precipitate.

Problem 3Difficulty: Mastery

Across CH4, NH3, H2O, and HF, why do boiling points not simply follow molar mass?

AOnly the number of protons in carbon controls all boiling points.

BPolarity and hydrogen bonding strongly affect intermolecular attractions.

CAll four substances are ionic lattices with identical attractions.

DMolar mass never affects boiling point in any substance.

Solution & Explanation:Molar mass matters, but molecular polarity and hydrogen bonding can dominate for small molecules. NH3, H2O, and HF have strong hydrogen-bonding interactions compared with CH4.
