During today's Chemistry class, we described the electron configurations for the atoms for any element using orbital notation, electron configuration notation, and, when appropriate, noble-gas notation.

Define that beta particles are composed of high speed electrons
Discuss how they are emitted from the nucleus to stabilize the atom.
Use Carbon-14 as the example and write the nuclear reaction to show the conversion of unstable carbon 14 into stable nitrogen 14
Student will complete the reactions for the conversion of potassium 40 and strontium 90 into calcium and yitrium respectively.

In today's class, we continued our discussion on ionic compounds, including what they are and how they are formed. We also began an introduction into naming ionic compounds, in which Andrew learned the rules on how to properly name each compound.

Define and discuss radiation, radioactivity, and unstable nuclei.
Introduce the 3 basic forms of radioactive decay: the alpha particle, the beta particle, and the gamma ray.
Show a typical alpha decay reaction using uranium conversion into thorium.
Write the equation and show how to work it backward to determine the new element formed from the helium nuclei decay. (alpha)
Write down 2 decay equations to be completed.

In today's class, we finished our discussion on ions, including what they are and how they are formed. We then began talking about ionic compounds, including how they are formed and what properties they exhibit.

In today's class, Andrew finished his worksheet on lewis structures, where he was given sets of molecules and he had to draw the lewis structures for them. We then began talking about ions, including talking about how they are formed, what charges they hold, and their formulas.

Examine how elements are arranged in the periodic table, both horizontally and vertically.
Show how and why the atomic radius changes as atoms move down the table and across.
Discuss how the radius will affect the activity.
Show on video the chemical activity of atoms in a family, and how they change with the location of the element.

Indicate both possible written formulas for water.
Using a whiteboard, demonstrate the ionization of water (HOH) into hydrogen ions and hydroxide ions.
Elicit why water test neutral for acid or base.
Outline an ionization of HCl when placed in water, showing both the ionization of the HCl and the HOH.
Show that the concentration of H+ ions increases when summed together, making the solution acid.

During today's classes, we continued working on Aufbau's Principle. Jaydn completed several activities.

In today's class, we continued our work on lewis structures. Andrew was given practice problems where he was presented with different molecules and he had to draw the lewis structures for them. Andrew did very well answering the problems on his own.
