Today in class we learned about atoms. We talked about electrons, protons, the structure of an atom, and the elements in the periodic table. An atom is the smallest unit of an element. Inside the atom there are energy levels, and then there are electrons on those energy levels. Then inside that theres a ball of neutrons and protons that make a nucleus. Then our teacher started to talk about the periodic table and what kinds of different elements there are. He told us that if you look at an element on the table you can see the element's name, the atomic number, the element's symbol, and atomic mass.
The class then started the lab. We were going to make hydrogen. We had a balloon, a beckon full of water, critic acid, magnesium metal, and citric acid, and an empty beckon.
We, my table partners, twisted magnesium metal, put it in the beckon thats empty, and poured the citric acid into it. Then slowly we poured the water to combine with the acid. Then we attached the balloon to the top of the beckon. The balloon started inflating with helium that was being made at the bottom of the beckon. When there was no more magnesium metal, we tied the balloon and had some fun with it.
After that we got a few students get there balloon and pop it with fire. It was a really funny experiment because everyone screamed when the balloon popped.
