In this lab we learned about atoms and how elements react with each other. We learned that the main subparticles of an atom are protons (positive), neutrons (neutral), and electrons (negative). The protons and neutrons are in the nucleus which are in the middle of the atom and the electrons are in energy levels that the atom would have. By looking at the periodic table, you can find out how many energy levels an element has by looking at the row it is in and how many electrons are in the outermost level by looking at the column it is in. An example of this would be oxygen, it is on the second row so it means that it has two energy levels and it is in the sixth column meaning that there are six electrons on the outermost level of the atom. Atoms like to have a full outermost level and a full outermost level for oxygen would be eight electrons, in order to get a full level, the atom must either gain or lose electrons from other elements. An example of this would be water, which is h2o so the outermost level of the oxygen atom needed two more electrons so it took one electron from each of two hydrogen atoms(hydrogen only has one electron) to fill up the outermost level and it completed it.
This experiment was to learn how do elements combine with each other. We experimented by combining hydrogen with energy from fire. At first we had to make hydrogen. In order to make hydrogen, we had to put the magnesium in a flask, then we put in 20 grams of citric acid, and then added 150 mL of water into the flask too. After we added the different elements in, we had to act quickly and cover the top of the flask with a balloon. The balloon should keep the hydrogen being made in one place instead of floating in the air. With the hydrogen balloon, we had it contact fire which releases energy to it that made it pop.
What happened was that hydrogen is a combustible gas and we had it contact fire so it would explode. My understanding of what happened it that the hydrogen balloon contacted with the fire that made it combust. When the fire was contacted it would have made h2o and probably made some water vapor on the balloon before it exploded. Someone told me that the reaction is kind of like a phase change from gas to liquid because the hydrogen turned into h2o.
