Below are sample questions representative of the exercises included on this worksheet and related 9.26 Groups, Periods, and Element Families skill assessments:

Problem 1Difficulty: Mastery
Which phrase best completes this pattern: Group 1 below hydrogen means alkali metals; Group 2 means alkaline earth metals; Group 17 means halogens; Group 18 means noble gases; Groups 3-12 mean what?
Anoble gas family
Balkali metal family
Chalogen family
Dtransition metal family
Solution & Explanation:Groups 3 through 12 are the central transition-metal region of the periodic table.
Problem 2Difficulty: Mastery
A student sorts Na, Mg, Al, Si, P, S, Cl, and Ar into one family because they are in the same row. Which correction is most accurate?
AThey form Period 3, but family labels depend on group location.
BThey are all noble gases because argon is included.
CThey are all halogens because chlorine is included.
DThey are all transition metals because the row is horizontal.
Solution & Explanation:A horizontal row is a period. Period 3 contains multiple families, so group location is needed to identify each family.
Problem 3Difficulty: Mastery
Two unknown elements are in the same period. Element X is in Group 1 below hydrogen, and element Y is in Group 17. Which comparison is correct?
AX and Y must be in the same family because they share a period.
BX is an alkaline earth metal, and Y is a noble gas.
CX is a noble gas, and Y is a transition metal.
DX is an alkali metal, and Y is a halogen.
Solution & Explanation:Elements in the same period can belong to different families. Group 1 below hydrogen indicates alkali metal, and Group 17 indicates halogen.
