Arsenic appears in two different forms: black and grey. The stable form or metallic form is grey and is brittle and crystal solid. It dulls at a high speed in air and at higher temperatures, burns producing a white cloud of Arsenic trioxide As2O3. The non metallic form is black and less reactive but will dissolve when heated at high temperatures with acids and alkali's. http://www.lenntech.com/periodic/elements/as.htm



This is a picture of someones hands with too little arsenic. This can and may cause small warts or corns and changes the color of your skin as you can see. To much arsenic can cause you to die.

Arsenic is a toxic substance that is commonly found in food, water and household items. A few examples of products with arsenic poisoning would be: sea food, laundry detergent, and drinking water. In seafood most marine fish and other creatures have naturally high amounts of arsenic in them, which means they are born with it. This type of arsenic is known as "Fish Arsenic". Some symptoms of arsenic poisoning can be headaches, problems with your lungs, kidneys or liver, suspect of skin cancer, and in some cases, convulsion and even death. Usually, arsenic poisoning is found by analyzing hair strands. Once diagnosed with, or suspecting you have arsenic poisoning, having sulfur or fiber in your diet can help get rid of some of the arsenic from your body. Chelation therapy is also an option for victims of arsenic poisoning. This type of therapy is a series of needles containing ethylenediaminetetra ascetic acid (EDTA) that is done in a doctors office. http://www.essortment.com/arsenic-poisoning-symptoms-treatments-63413.html

Some precautions of being around or using arsenic are: wear gloves, do not allow on or near skin, wear goggles, wear a lab coat or a shirt with long enough sleeves so no skin is showing.

"Millions in Bangladesh exposed to arsenic in drinking water"- http://articles.cnn.com/2010-06-20/world/bangladesh.arsenic.poisoning_1_arsenic-mass-poisoning-bangladesh?_s=PM:WORLD This article talks about the toxic levels of arsenic in Bangladesh's water last year around June.




Our opinion of the use of arsenic is that you should have just enough. Not too little or too much but in the middle. I think this because if you have too little, your skin can change colour and you can get warts, but if you have to much arsenic, you can die. We think Arsenic is something that should be kept in everyone's life, but kept under control.

  4. Lots of great stuff so far, a couple of suggestions: a) do you know what the numbers up at the very top with your atomic model mean? if not try to find out, see me if you have troubles
    b) can you add some information to the picture with the hands so that we know exactly what it is we are looking at.
    Keep up the good work!
