Video #2  Element Rectangle

(Feb 5) In support of Handout #54, this video explains what information can be found in an element's rectangle on the periodic table.  There is also a dire warning against misguided capitalization.

Also, how do we calculate an element's neutrons?

Video #3  Electron Shells

(Feb 5) In support of Handout #54, this video explains the concept of electron shells within an atom's electron cloud.  This also shows how we calculated the maximum number of electrons each shell can hold.  

Video #4  Element Classifications

(Feb 10-14) In Handout #51, you were asked to research the eight element classifications within the periodic table.

Video #7:  Post Transition Metals & Metalloids

(Feb 10-14) So, you don't wrap food with tin foil.  You say 'tin' foil because grandma said it, your folks said it and now . . . Well, it's not your fault.  It's called aluminum foil.  Also, what is the most important metalloid?  Your technology is driven by element #14, silicon.

Video #8: Other Non-metals

(Feb 10-14) These are us!  98% of the atoms in our bodies (and most living things) are the other non-metals: C, H, O, N, P, S.  We are considered carbon-based life forms, not because it is our most abundant atom (H is first, followed by O).  Carbon is the great unifier -- it is the atom that allows large molecules such as proteins, enzymes and DNA to be put together.

Video #9: Halogens & Noble Gases

(Feb 10-14) Rounding out the final two classifications are the halogens and noble gases.  Halogens have 7 valence electrons and are a natural match with the alkali metals (7 + 1 = 8).  In Group we find the noble gases.  With the exception of He, noble gases have 8 valence electrons and will not bond with any atoms, even themselves.

Video #10:  Electron Configuration #1

(Feb 18-19) In support of Handout #56.  

Each of you was asked to draw the electrons (in their shells) for atom #19, potassium.  Since potassium has 19 protons (+'s), it has 19 electrons (-'s).  You all drew it incorrectly (2,8,9).  Perfect!  That's what we were hoping.   

Video #11:  Electron Configuration #2

(Feb 19-20) In support of Handout #56.   

This was recorded last year, so Mr. Wright refers to  Handout #60, not this year's #56.

Video #12:  Electron Configuration #3

(Feb 19-20) In support of Handout #56, we begin slowly with the s, p, d & f madness.  You will all get this.  OK? 

Potassium is on the 4th row of the periodic table.  This means that it has 4 electron shells.

Video #13:  Electron Configuration #4

(Feb 19-20) In support of Handout #57.  

Let's talk about and configure elements on the first two rows of the periodic table.

This was recorded last year, so Mr. Wright refers to  Handout #61, not this year's #57.

Video #14:  Electron Configuration #5

(Feb 19-20) In support of Handout #57. 

Neon to Argon.  Plus, where do we go after ending the 3rd column? 

Video #15:  Electron Configuration #6

(Feb 19-20) In support of Handout #57. 

This was recorded last year, so Mr. Wright refers to  Handout #61, not this year's #57.
