My inert gas of the week is Argon. Argon's chemical symbol is Ar and its number is 18. According to Wikipedia, Argon is present in the Earth's atmosphere at 0.94%. Argon was isolated in 1894 by Lord Rayleigh and Sir William Ramsay in Scotland.
Colors of foods in my kitchen
I am pretty embarrassed by the colors of foods in my kitchen. I went out of town last weekend and haven't spent any time at home so I haven't gone to the grocery store in some time. Most of the colors come from fruits and vegetables. Green in lettuce and peas, an orange, some orange squash and yams. Some of my cereals have dried berries that are pretty brightly colored. Other then that, everything is brown and beige. I'm sure that will change after I go to the store tomorrow.
This week's links
I found this week's links very interesting. I really liked the link "Color of Elements in a Flame." It was really cool to see pictures of the flames and I guess it connects to our discussion on fireworks last week. I also found the article "Luminescence and Fluorescence" interesting. I never realized that there are so many forms of luminescence. It makes sense that there would be, I just never really thought about it. It reminded me of when I went to a marine biology camp on Catalina Island as a kid. We had a night class that discussed bioluminescent fish which I found very fascinating.
I'm curious which color will be added in your kitchen tomorrow.
ReplyDeleteIt is amazing that you still have some colors even though you haven't gone for grocery shopping.
If it's in my case, you'll see nothing in my fridge...
