Chemistry

First of all, I will give you a little quiz.

1. What does C12H22O11 stands for, and what is it?
2. What do you get if you mix a strip of zinc foil and dilute hydrochloric acid?
3. List the first ten elements of the Periodic Table.

Confusing, and for those who don't know anything about chemistry, doesn't make sense at all, eh? Well, you're lucky to have Marshall (me) as your part time chemistry guide !

Chemistry is a subject about atoms, chemical relationships, chemical reactions and all the other things that might be nonsense to you.

The first thing that you all have to know about chemistry is about the structure of an atom. Atoms are so small that about 10 to the power of 18 carbon atoms in the full stop at the end of the sentence. There a three types of subatomic particle (look in a scientific dictionary):

  • Protons (positive charge) - found inside the nucleus.
  • Neutrons (neutral) - found inside the nucleus.
  • Electrons (negative charge) - arranged in energy levels around the nucleus.

All atoms contain these particles - except the lightest atom, hydrogen, which contains no neutrons.

That is all I'm writing today. Thank you for reading this blog message.

  2. excellent work marshall! did yo uuse a website to ge tyou rinfo? if so, say what it was and list the url
    i find the periodic table abbreviations for each element very cool. i like "fe" for iron.
    lets learn them in class...

  3. thank you Mr Woody! :-)) i got my idea from my trusty old NCEA lvl 1chemistry book. the whole post is in my own words, edited by a bit of creativity. studying chemistry in class will be SO COOL!!

  4. You are going to be hard pushed for top scientist this year, because I will be your top compeditor! My father is a chemistry teacher, and can give our loooong and boring lectures, but he does give out loooongs nd interesting lectures too. For instance - what are chromazones?
    Are you doing the science Australasian test this year?

  5. um... er... i think chromosoms- no, wait... kromasone... that chromosomething is in biology, not chemistry. and... yeah - i will do the australasian test this year, plus i got a distinction last year.

  9. CRAZY for my brain!
    But chemistry is cool!
    Coke and Mentos!
    WARNING!
    Don't have them together!

  10. i found this on the internet,it's info on how the periodic table of elements developed:
    http://www.wou.edu/las/physci/ch412/perhist.htm
    i'm pretty sure the first 36 elements on the periodic table are:
    1.hydrogen
    2.helium
    3.lithium
    4.beryllium
    5.boron
    6.carbon
    7.nitrogen
    8.oxygen
    9.fluorine
    10.neon
    11.sodium
    12.magnesium
    13.aluminum
    14.silicon
    15.phosphorus
    16.sulfur
    17.chlorine
    18.argon
    19.potassium
    20.calcium
    21.scandium
    22.titanium
    23.vanadium
    24.chromium
    25.manganese
    26.iron
    27.cobalt
    28.nickel
    29.copper
    30.zinc
    31.gallium
    32.germanium
    33.arsenic
    34.selenium
    35.bromine
    36.krypton

  11. exellent work, kitty milo! sorry i didn't reply the last few days. my dad had to disconnect the computer!
    P.S i went to the website you wrote. it has the discriptions of the elements, very cool!
