Chapter 8: Problem 82

Without referring to any tables or listings in the text, mark an appropriate location in the blank periodic table provided for each of the following: (a) the fifthperiod noble gas; (b) a sixth-period element whose atoms have three unpaired \(p\) electrons; (c) a \(d\) -block element having one \(4 \mathrm{s}\) electron; (d) a \(p\) -block element that is a metal.

Short Answer

Expert verified
The solution to the exercise is: a) Xenon (Xe) b) Polonium (Po) c) Scandium (Sc) d) Aluminium (Al)

Step by step solution

01

Identify the fifth-period noble gas

Noble gases are found in group 18 of the periodic table. To find the fifth-period noble gas, move down to the fifth row and then across to group 18. This is element Xenon (Xe).
02

Find a sixth-period element with three unpaired p electrons

This refers to elements in the nitrogen group (Group 15) as elements in this group have 5 electrons in their outer shell, 2 of which are paired, leaving 3 unpaired. We need the element in the sixth period, and that will be Polonium (Po).
03

Locate a d-block element with one 4s electron

The presence of one 4s electron means that this element has already filled the 3d sublevel and moved onto the 4s sublevel. The elements in the first column of the d-block represent this configuration. In the fourth period, the element that matches this rule is Scandium (Sc).
04

Identifying a p-block metal

Moving to the right side of the periodic table, most of the metals in the p-block are found in groups 13 and 14 (also known as the Boron and Carbon groups). One metal from this block can be Aluminium (Al), located in the third period of group 13.

What is the expected ground-state electron configuration for each of the following elements? (a) mercury; (b) calcium; (c) polonium; (d) tin; (e) tantalum; (f) iodine.

Although Einstein made some early contributions to quantum theory, he was never able to accept the Heisenberg uncertainty principle. He stated, "God does not play dice with the Universe." What do you suppose Einstein meant by this remark? In reply to Einstein's remark, Niels Bohr is supposed to have said, "Albert, stop telling God what to do." What do you suppose Bohr meant by this remark?

Draw an energy-level diagram that represents all the possible lines in the emission spectrum of hydrogen atoms produced by electron transitions, in one or more steps, from \(n=5\) to \(n=1\).

Construct a concept map for the configurations of multielectron atoms.

The Pfund series of the hydrogen spectrum has as its longest wavelength component a line at \(7400 \mathrm{nm}\) Describe the electron transitions that produce this series. That is, give a Bohr quantum number that is common to this series.
