This is a preview of the pubished version of the quiz Started: Sep 18 at 12:47pm Quiz Instruc!ons Homework 05 - H Atom and Eectron Configuration Question 1 Which of the foowing experiments provided evidence that the eectrons in atoms are arranged in distinct energy eves? the resuts of the Miikan oi-drop experiment the scattering of apha partices by a meta foi the observation of ine spectra from gas discharge tubes the existence of eements with non-integer atomic weights Question 2 Assume n and n are two adjacent energy eves of an atom. The emission of radiation 1 2 with the ongest waveength woud occur for which two vaues of n and n? 1 2 7,6 4,3 2,1 8,7
2 Question 3 Use the Rydberg formua for atomic hydrogen to cacuate the waveength of the photon emitted in the transition of an eectron from n=4 to n= nm 8.63 nm 205 nm 486 nm Question 4 What is the name given to the spectroscope series to which the transition described in question 3 beongs? Bamer series Paschen series Lyman series Brackett series Question 5 In what region of ight wi the photons emitted in question 3 ie? visibe, bue visibe, red

B There is no way to know. A Question 7 What is the maximum number of eectrons that can have the quantum number n=2 in an atom? 18 6
4 2 8 Question 8 The three quantum numbers for an eectron in a hydrogen atom in a certain state are n=4, =2, and m =1. The eectron is ocated in what type of orbita? 3p 3d 4d 4p Question 9 The number that describes the main energy eve of an eectron in an atom is... the atomic number, Z. the anguar momentum quantum number,. the principa quantum number, n. the magnetic quantum number, m. Question 10 Can an eectron in an atom be in an energy eve described by the set of quantum
5 numbers n=5, =3, m =-2? No, because m cannot be negative. No, because must equa n-1. No, because m must equa ±1. Yes. Question 11 An eectron in a 3d orbita coud have which of the foowing quantum numbers? n=3, =1, m =-1 n=3, =3, m =1 n=3, =2, m =0 n=3, =2, m =-3 Question 12 How many p eectrons does Se (atomic number 34) possess?

This observation can be expained (theoreticay) by the fact that... the 4d subenergy eve has higher energy than the 5s subenergy eve. an enhanced stabiity is associated with fied sets of equivaent orbitas. the magnetism measurement shows one unpaired eectron. ony one eectron can occupy a 5s orbita. Question 20 Which of the foowing atoms has the argest radius? N C F Br
9 Question 21 As an atom's radius decreases... its ionization energy increases. its ionization energy wi either increase or decrease depending on whether you are going up a coumn or across a row. its ionization energy does not change. its ionization energy decreases. Question 22 Which of the foowing woud be expected to have the highest first ionization energy? Na Si Xe C Ar Question 23 How many s eectrons does P (atomic number 15) possess? 4 2
10 5 6 Question 24 How many vaues of the quantum number are possibe when n=5? Question 25 How many vaues of m are aowed for an eectron in a 5f subshe? Question 26 How many vaues of m are aowed for an eectron in a 2s subshe?
11 1 None of these. 4 3 Question 27 How many subshes are there in the she with n=3? Question 28 The diameter of the eectron density of an atom is roughy... None of these nm nm 1-5 nm Question 29
12 For which of the foowing eements woud the size of the neutra atom (atomic radius) be the argest? Rb Na Sr Ca Question 30 Write an equation that represents the second ionization energy of nicke Ni (g) Ni (g) + e 2+ - Ni(g) Ni (g) + e Ni(g) + - Ni (g) + e 2+ - Ni(g) Ni (g) + 2e Quiz saved at 12:48pm Submit Quiz
