CHEMACTIVITY 23 CRITICAL THINKING QUESTIONS

The radius of the outer shell in Li is larger than the radius of the inner shell. How many carbon atoms are present in this diamond? How long did it take for the reaction to come to equilibrium? If you have How many trunks are found in one mole of elephants?

The relationship between acidity, pH, and the hydronium and hydroxide ion concentrations of a solution. For each of the following species: This is essentially a plot of the number of ejected electrons along the vertical axis vs. Give your answer in terms of a number such as 17 or 3. To the Instructor These activities are designed to be used by students working in groups.

The central atom is the first atom listed other than hydrogen. Given the definitions of the terms hypotonic and hypertonic, what do you suppose an isotonic solution would be? Criticall Shell Model and Ionization Energies.

Domains of electrons around a central atom will orient themselves to minimize the electron-electron repulsion between the domains. Michael Garoutte Missouri Southern State University July Some comments from former students in this course I thought that I wouldn’t like this class but it has been really interesting to come to class every day and actually qiestions something that pertains to life.

Classify each of the following bonds as nonpolar, polar, or ionic. The resolution of this apparent inconsistency is that although He has only 2 valence electrons, its valence shell is completely filled.

Report your answer with the correct number of significant figures. Describe dritical a word or short phrase the shape of each of these molecules: For each type of compound below, indicate how the boiling point changes as the molecular weight of the compound increases: Since both bonds are equally polarized in opposite directions, no particular side crtiical end of the CO2 molecule is negatively or positively polarized.

Minimization of electron-electron repulsion leads to a unique geometry for two, three, and four domains of electrons. Some of the following Lewis structures are missing formal charges. In all cases, the ionization energy decreases as we move down the group. Answer the following for the nitrogen atom: Also, because the photons used all have the same energy, electrons ejected from a given energy level will all have the same energy.

One concept we need to work on is: What is the density of the tin? How many electrons in the dot structure for C are paired? Their enthusiasm for this approach, patience with our errors, and helpful and insightful comments have inspired us to continue to develop as instructors, and have helped us to improve these materials immeasurably.

This scale has sincebeen refined based on more recent experimental evidence. Draw the Lewis structure, sketch the molecules, predict the molecular shape, and give the bond angles for: Types of Electron Domains. Round each of the following to three significant digits. Note that this is the same reaction as in CTQ 3, but with the spectator ion potassium included.

We can represent the Li atom in terms chemactivjty core charge as shown in Figure 1. Consider the CCl4 molecule. Without referring to a table of electronegativities, identify the most electronegative atom in each case: How does the number of protons in the reactant compare with the total number of protons in the products?
