Electron Configurations and Periodic Trends

Electron Configurations

These are covered in great detail in SECTION 7 - Quantum Mechanical View of the Atom and Periodicity, so we'll only review them briefly here today.

Electron Configuration = the arrangement of electrons in energy levels around an atomic nucleus.

The Diagonal Rule:

There...

Wave-Particle Duality, de Broglie Wavelength, and Photoelectric Effect

Quantized Energy

The Nature of Matter - In the early 1900's, Max Planck discovered that matter cannot absorb or emit any amount of energy.

Instead...

He postulated that energy can only be gained or lost in whole-number multiples of the quantity hv 

    so, the change in energy...

Cell Potential Calculations and Line Notation

How to Calculate Galvanic Cell Potentials (Ecell)

We must first consider the standard reduction potentials for each half-reaction:

    E°cell

    values are listed in Table 17-1 of my *Chemistry Video Notes,* and also below...

Table 17-1 = Standard Reduction...

How to Calculate Energy, Work, and Heat

Two key definitions before we begin:

- thermodynamics = the study of energy and its interconversions.

- 1st Law of Thermodynamics = the total energy of the universe is constant.

=====

The Internal Energy of a System (E)

- think of the "system" as the "chemical reaction."

The Internal Energy of a...

What is Entropy? Entropy Changes in Chemical Reactions

Second Law of Thermodynamics

2nd Law of Thermodynamics  =  the entropy (S) of the universe is constantly increasing. In any spontaneous process, the entropy of the universe increases.

The change in entropy of the universe is given the symbol, ΔSuniv

if ΔSuniv > 0 ,...

Boyle's Law, Charles' Law, and Avogadro's Law

The Gas Laws

Today we're going to talk about the three gas laws (in order): Boyle's Law, Charles Law, and Avogadro's Law.

Then, we'll move on to the Combined Gas Law and the Ideal Gas Law.

First, the three gas laws...
