(a) What is meant by the term state function?
(b) Give an example of a quantity that is a state function and one that is not.
(c) Is the volume of a system a state function? Why or why not?
Step 1 of 5) (a) What is meant by the term state function(b) Give an example of a quantity that is a state function and one that is not.(c) Is the volume of a system a state function Why or why notAs we move beyond the s block, from element 56 to element 57, the curved arrow below the periodic table reminds us that we are entering the f block. The first row of the f block corresponds to the 4f subshell. As we move across this block, we add 14 electrons: 4f 14. With element 71, we move into the third row of the d block. Because the first row of the d block is 3d, the second row is 4d and the third row is 5d. Thus, as we move through the ten elements of the d block, from element 71 to element 80, we fill the 5d subshell with ten electrons: 5d10. Moving from element 80 to element 81 puts us into the p block in the 6p subshell. (Remember that the principal quantum number in the p block is the same as that in the s block.) Moving across to Bi requires three electrons: 6p3 . The path we have taken is: Putting the parts together, we obtain the condensed electron configuration: 3Xe46s2 4f 145d106p3. This configuration can also be written with the subshells arranged in order of increasing principal quantum number:
