Question
hi guys i need help in chem quiz
question 7
question 8
Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, I, mf and mps) 3,3,3,1/2 2,2,-1,-1/2 1,0,0,1/2 3,3,3,-1/2 5,4,-5,1/2 Which of the following would have the largest second ionization energy? C N K S Which electron configuration represents a violation of the Pauli exclusion principle? Which electron configuration represents a violation of the Pauli exclusion principle? Which electron configuration represents a violation of Hund's rule for an atom in its ground state? Which one of the following atoms has the largest radius? I Sr Co Ca Ba
Explanation / Answer
maximum value of l=n-1
m=+/-1/2
hence option c
2.
N would have highest second ionization energy because after removal of 1 electron it would reach stable state and henec high energy required .
3.c) direction of spin should be opposite
4.b) electron should be filled in lower states first
5.Iodine
