An atom is a unit of an element. Atoms are everywhere. They include three subatomic particles which are, protons, electrons, and neutrons. A Proton has a positive charge and is located in the center of the nucleus. A Electrons are the opposite of a proton. They carry a negative charge and orbits around on the second layer of the nucleus. However the Neutron doesn't carry a positive nor negative charge. It stands for neutral, they are located inside the nucleus.
As for the experiment, the materials we used were:
- A volumetric flask
- Small beaker of water
- Small beaker of citric acid
- A string of magnesium
Our goal was to fill up the balloon with hydrogen to have it float into to the air. Hydrogen is sort of like a helium related chemical. We were observing what reactions happened during the process.
We were to break up a couple pieces of magnesium in the flask then pour in the water and citric acid. A couple minutes after, the magnesium starting reacting with the acid. We immediately put the balloon on the top of the flask so that it could collect the hydrogen right away. We let it sit for a while allowing the balloon to fill up as much as it could. The magnesium runs out and tie off the balloon. In order to have the balloon rise and become lighter we cut the end off. And finally at the end we put it over candles, that causes the balloon to pop into the air.

Our group noticed that once all three ingredients came in contact with each other it started to bubble up. After a few seconds the bottom of the flask began to warm up. We predicted that the citric acid and magnesium started to take over the hydrogen to inflate the balloon with. Something that we observed also was the the hydrogen filled up so fast that the balloon could not handle. Two bubbles were forming inside, therefore we had to push up to make sure it wouldn't explode.
This was definitely a really cool experiment. We've done something similar to this before as a lab. It made me think of the dry ice lab we did a while ago, the balloon that we used for the dry ice experiment just filled it up. This time the balloon was inflated with hydrogen to make it rise. I worked with my group very well. We were able to collaborate and help each other develop ways to understand how the atoms are working.
