Below are sample questions representative of the exercises included on this worksheet and related 11.17 Quantum Model and Electron Configurations skill assessments:

Problem 1Difficulty: Mastery
A table lists four particles. Which particle has an argon electron configuration and a +1 charge?
AParticle A
BParticle B
CParticle D
DParticle C
Solution & Explanation:Argon has 18 electrons. A +1 charge means protons exceed electrons by 1, so the particle with 19 protons and 18 electrons is the correct choice.
Problem 2Difficulty: Mastery
A configuration is written as [Xe] 6s2 4f14 5d10 6p2. Which statement best identifies its block and highest occupied principal energy level?
AIt is an f-block configuration with highest occupied n = 4.
BIt is a d-block configuration with highest occupied n = 5.
CIt is a p-block configuration with highest occupied n = 6.
DIt is an s-block configuration with highest occupied n = 6 only if 6p is empty.
Solution & Explanation:The configuration ends in 6p2, so it is p-block. The highest principal level present is n = 6, from 6s and 6p.
Problem 3Difficulty: Mastery
Which species has a noble-gas configuration and a +1 charge?
AAr
BK^+
CCl^-
DCa2+
Solution & Explanation:K^+ has 18 electrons, the same as argon, and its charge is +1. Ar has no charge, Cl^- is -1, and Ca2+ is +2.
