Mid Term Exam Review Question # 20

For this blog I was assigned question # 20(a,b, and c) on our exam review. The questions are....

a) What is the most common charge on an ion from Group 6A (group 16)?
b)What is the most common charge on an ion from the group 2A (group 2)?
c) Using your answer from b, where would you except a sudden jump among consecutive energies and why?

A) Group 6A or group 16 starts with the element O, or Oxygen. The most common charge on an ion that would form would be 2-. These elements form 2- ions because theses elements have a intensely high ability to add two electrons inorder to have the stable electronic configuration of a noble gas.

B) Group 2A or group 2 starts with the element Be, or berillium. The most common charge on an ion that form is 2+. These elements also want to have the stable configuration of a noble gas, so they take away 2 electrons inorder to get that electronic configuration.

C) Because the elements in group 2A form ions with a charge of 2+, there will be a sudden increase in ionization energy when you take away the 3rd electron, or IE3, from these elements. Because these elements for ions with a charge of 2+, a stable noble gas configuration, it takes an extreme ammount of energy to take away the next electron because these elements already have that stable configuration.

Ernest Rutherford's Gold Foil Experiment

For this blog assignment I decided to look deeper into the Experiment that founded the nucleus, the Gold Foil Experiment. When we were going over this experiment during class, I didn't really understand why the alpha particles were deflected and how this founded the discovery of the nucleus. If you click on the link to my glogster below, all you chemistry dreams will come true! Enjoy!

Here is a link to my Glogster!

Here is also a Youtube Video that further explains the Experiment:

After conducting my research I realized that the significance of this experiment was that current plum pudding model of the atom was incorrect and that because of the waythat the alpha particles bounced off the gold foil showed that the majority of the mass of the atom was concentrated in one small area (the nucleus). Since most of the positive particles continued on their original path undeflected, Rutherford assumed that the rest of the atom was made up of empty space. Rutherford termed his discovery "the central charge," and it is now called the nucleus. Rutherfords discovery lead to the Bohr model of the atom and the developement of nuclear physics.

Chemical and Physical Properties of a Jet-Puffed Marshmallow!


For this assignment I decided to observe the chemical and physical properties of a marshmallow. A marshmallow is a very common object that is essential to kid's daily lives. I chose this object because I never really thought of its chemical or physical properties. I just looked forward to shoving it into my mouth.

Chemical Properties:
1. Roasting the Mallow (Everyone's favorite)
As I roasted the marshmallow, and as it caught on fire it started to burn around the outside. When I burnt the marshmallow, it caused a chemical reaction, forming a new substance (the burnt part) and changing its composition.

2. Boiling Marshmallows with Malt Vinegar

To execute this experiment, I added some marshmallows to a pot and added some Malt Vinegar and boiled it. This produced a chemical reaction and the marshmallows evaporated.

3. Marshmallow in Nail Polish Remover
When I did this experiment, i filled a container up with nail polish and put the marshmallow in it. Nothing happened. Marshmallows do not react to nail polish remover.
4. Marshmallow in Hydrogen Peroxide
When I executed this experiment i put hydrogen peroxide in a small container. When I put the marshmallow in the container nothing really exciting happened. Marshmallows do not react to hydrogen peroxide.

5. Marshmallow in Kaboom
When I put the marshmallow in a small container of Kaboom, nothing really big happened. The only thing I observed was that it dissinegrated a little bit but not a lot.

Physical Properties:

1. Density: 0.37 g/ml
2. Diameter: 3cm
3. Squishy, foamy, and soft composition 
4. White color
5. Expands with heat:
I was curious of what would happen if I put marshmellows in the microwave. When I did they expanded and the insides turned gooey


In conclusion, the marshmallow was a tough object to pick. In fact, it hardly reacted to anything I put it in. I wish I would have picked an easier object. But atleast eating the roasted marshmallows was fun!
