Week 25 Reflection

This in our 25th week of chemistry Mr. Abud had ask all the question we had to so the class would be able to move forward and advance. I presume it just to make sure everyone understood the material, so we all could and be ready to go onto some new information for the 4th and final quarter at least for me. Some of the question that were asked were about ions, what are they made of and how do they bond, myself I already knew that. But a couple others were confused on how the opposite charges made a bond? Because if the charges are trying to neutralize each other and there can be an unequal amount of charges in one element how can they be made equal? Mr. Abud explained the amount of positive or negative charges must equal the other, if one element has more charges in a single atom then the other element with a smaller needs more of it to counter balance the equation. What I don’t understand what the difference between ionic and molecular bonds other than Ionic bond are made from a non-metal and a metal and a molecular bond is made form a metal and a metal. Other than that I don’t really know much about what the difference is. First he told that ions were formed from an overload of negative charges or a scarcity of positive charges. Then I learned that an ionic (or electrovalent) bond is formed between two ions of opposite charges. During the formation of an ionic bond, one of the reacting elements should form a positively charged ion (cation), and the other should give a negatively charged ion (anion). And that a molecular bond is formed well to tell the truth kind of forgot and didn’t write it down but ill ask him next! Anyway we got onto the top of conductivity and well that simple enough metals are very good conductors of electricity. And things that don’t conduct electricity are called insulators, which have low conductivity. Some examples of Isolators are wood, plastic, and rubber, which is why there are rubber layers over wires so we don’t get shocked because we as humans are conductors because of the electrons and water in our bodies, which is very conductive to electricity. Another interesting piece of information we learn and went over is that balloons when charged it will attract to insulators and nor conductors, I especially found this weird because if a balloon is charged with negative charges wouldn’t it want to attract positive charges like in a wall. The whole thing had me kind of confused… so I don’t remember, but again I will find out! I always do. Later in the week we did an electrolysis experiment with copper chloride. We were trying to see using electricity if we could separate the copper from the chlorine. We mixed the water and some substance in the container with metal rod, and would allow the electricity to flow. After making electricity run through the water, the copper would attract to the negatively charged rod, because copper has a plus 2 (2+) charge and that “opposites attract!” which we all were told in grade school. After we finished the experiment we dumped out the solution, we saw that we were right the copper stuck to the negatively charged rod. And chlorine attracted to the positively charged rod. The electricity split the two elements and the ionic compound with it. I find it funny how just a little electricity caused by friction by between gears and change something so small, but in turn it’s very fascinating! I can’t wait tot see what we do next! Till next time.
