Help!!! My 7th grader needs to make a 3-d model of the element Silicon..

Hello Mia7,

Could you please tell me what you want to make a model of, I think I know but I'm not completely sure.

An atom is made of three main parts. The neutron, proton, and electron. The neutrons and protons are squashed together in the center called the nucleus, and the electrons spin around the nucleus.

The electrons are negatively charged, and the protons are positively charged. The neutron does not have a charge but sticks with the protons and forms the nucleus. These attract each other and form the atom.

There are many different ways that you can make a model with. One of my favorite is to use styrofoam and tooth picks. This website talks about the different parts in more detail and might help you too. http://education.jlab.org/qa/atom_model.html

Hope this helps and please let us know how it goes.

Philip

Thank you so much! He has to make a 3-d model of the element Silicon.
I have started with a large styrofoam ball and cut in half, then I was going to use smaller styrofoam balls with toothpicks as well. I am just not sure how to label them correctly. The teacher wants all the protons, electrons, and neutrons labeled and put in the right place. It has to appear in 3-d so I am just trying to get it all in my head so we could do it correctly. If you have any other ideas please post.

Hi Mia7,

It sounds like you got the hardest part done already. As far as labeling, I would recommend color coding the different parts. Like making the neutrons green and the protons blue because it would be very difficult to write the exact label on every little part, or you can just write the letter like p for proton.

There are three main parts that you have to label. The big part in the center is the nucleus and has protons and neutrons. The other part is the electrons which go around the nucleus.

As long as you label the protons and neutrons in the nucleus and the electrons on the outside you should have everything covered. If you need some more help please let us know. Thanks
