It's Elementary my dear Watson

Elements

(this site will be under continual construction)







A Visual Periodic Table


A very complete resource for the Periodic Table from WebElements


Sodium and chlorine bonding ionically to form sodium chloride. Sodium loses its outer electron  to give it a noble gas electron configuration, and this electron enters the chlorine atom exothermically. The oppositely charged ions are then attracted to each other, and their bonding releases energy. The net transfer of energy is that energy leaves the atoms, so the reaction is able to take place.

An ionic bond (or electrovalent bond) is a type of chemical bond that can often form between metal and non-metal ions (or polyatomic ions such as ammonium) through electrostatic attraction. In short, it is a bond formed by the attraction between two oppositely charged ions.

The metal donates one or more electrons, forming a positively charged ion or cation with a stable electron configuration. These electrons then enter the non metal, causing it to form a negatively charged ion or anion which also has a stable electron configuration. The electrostatic attraction between the oppositely charged ions causes them to come together and form a bond.


Remember Robin Hood? The Sheriff of Nottingham?


Here you find a video about every element on the periodic table, COOL!








Follow the amazing connection of THE ELEMENTS AND LIFE.

(thanks to an excerpt from Media Wiley http://media.wiley.com/product_data/excerpt/52/35273206/3527320652.pdf)


Yes, some of the connections seem quite complex, but while you are reading take note of the simplicity of whole numbers that literally bind life together -





... a seeming Infinite Diversity in Infinite Combinations from so few (27) essential elements...
(don't forget to check for your element)

Thank goodness you had Life Science last year... and now , 4...5...6... almost a little spooky!

The last paragraph is about you. No, seriously, it really is about you!


A simple Practice Quiz.... Chem For Kids

A different perhaps more challenging Quiz ... Proton Don

And now an advanced (7th) Grade Quiz ... Quia Quiz

So, what do you think?
How did you do?

Find anything out about your element?

  1. Is the atomic weight mean the same thing as atomic mass?

  3. For the chemistry review video it say "not only the tendence of chemistry from the states of mater to the law of thermal dynamics usefull in scientific circles but are used in a wide range of automotive industries and also cooking" what does that mean -thanks jake yellow

  4. Is the vocab test thursday or friday -jake yellow

  5. You need to understand Chemistry, to understand all the other aspects they speak of i that introductory video. You can see Science at work in the Blog Video "Sweet Science"

  15. The Quiz is the one you guys made up for yourselves.

  16. Mr. V, I watched a video on potassium, and I thought it was very cool, and helpful on information on what happens when you mix it with sodium. I took the first quiz for kids and got all of them right. Then I took the second quiz, and I did a combination of levels on that game. I wasn't completely horrible at it, but I wasn't good either. I took the third quiz and got 12 out of 21. I think the last few I got wrong because of spelling errors, but I feel rather unintelligent at the moment. I failed a 7th grade quiz. I should be ashamed of myself. I am now going to research the rest of the things on this quiz so that I can recieve a Hundred percent on each of them.Other than that I found this blog relatively helpful. I have a few question though on the content of the slide thing. I will put them in my next post in a half an hour approximatly.

  17. My first question: what is a electrochemical
    transfer of signals in the nervous system? I know it has something to do with what or how your body signals things to other systems in the body but it confuses me.
    My secend question: what is silenium?

    I really don't understand the rest of it either, other than the fact that DNA is made of 4 components.

  18. YOU shouldn't feel bad about not doing well on the 7th grade quiz... now you know what you need to learn...How cool is THAT!!

  19. Selenium is a trace mineral that is essential to good health but required only in small amounts. Selenium is incorporated into proteins to make tha are important antioxidant enzymes. The "selenoproteins" help prevent cellular damage that may contribute to the development of chronic diseases such as cancer and heart disease.

    Pretty important stuff!

  30. Mr V, I had lost the rubric for our element project somehow and i need it for the rest of my project. Do you have a link of the rubric that i could use and print out for my element? Thanks. This would be a big help.

  31. Tyler, You can find a working Rubric in the "Elements for Life" Blog archive from December 15 2010. (You could copy and paste if need be.)

    It doesn't look quite like the handout because of different margin size but it should work for you.

    I hope this helps you.

  32. Thanks, do I have to turn that into you?

  41. What are the similarities of mass and weight?

    Lindsey - Green

    ReplyDelete
  42. One of the similarities is that people think they mean the same thing.

    If anyone needs help with the periodic table?
    If so read on. ( think about what we're studying in Mr. Nevins class 4.3 especially)

    Helium, Neon,Argon, Krypton, Xenon, Radon, and Ununoctium They're the plantation owners(noble gases) and self-sufficient.
    Independent small farmers(Metals) aren't self sufficient and need help to be whole. Nonmetals are immigrants that aren't considered high in society, but are still regarded. Slaves(transitional) aren't considered fully human(closer to animals) so they don't fit in with anyone.

    P.S. Hope this helps and I couldn't figure out who the Lanthanide and Actinide Series could be

  44. Skills Activity page 161
    Remember, Bromine is in the same group as Fluorine - so it will form an ion with the same charge as fluoride. Pair up positive and negative ions in RATIOS that result in neutral ionic compounds: NaBr, Li2O, MgS, AlF3, KNO3, NH4Cl.
