# 3d Model of a Carbon Atom

We know that any of the matter has mass and takes up space. It is composed of atoms which are also called as basic building blocks of matter. Atoms are considered as the smallest unit which cannot be chemically subdivided by normal chemical or physical methods. Atom word is derived from ‘atomus’ which means indivisible. Today we know that an atom is mainly consisted of three fundamental particles. These particles are arranged in a certain manner to give a stable atom. Put of these 3 subatomic particles, the mass of electrons is negligible therefore most of atomic mass of the atom is due to mass of protons and neutrons. Protons carry positive charge while electrons carry negative charge. Neutrons are neural particles and do not contribute in the charge of atom. The same number of protons and electrons in an atom makes it neutral as the positive charge is negative charge of the atom. According to Bohr’s model, the negatively charged electrons are arranged in circular paths which are called as orbitals around the nucleus. Nucleus which is placed at the center of the atom contains protons and neutrons. The total number of protons in an atom is called as atomic number which is also equal to the number of electrons in an atom. That is the reason; the atomic number is also used to write the electronic configuration of an atom. For example the electronic configuration of carbon atom is 1s2, 2s1, 2p2. The 3d-model of a carbon atom is as given below;

We can also make the 3d model of a carbon atom with the help of floral wire, 6 small styrofoam balls with 12 medium styrofoam balls. First paint 6 medium size balls with same color as all the protons of the atom must be of same colour such as orange.
Now take remaining 6 medium size balls and paint them with blue colour to show neutrons. Take 6 small balls and paint them with green colour. Mark ‘+’ charge on orange balls to show charge on protons and ‘-‘ on green balls of electrons with the help of marker.

Remember protons and neutrons must be of same size and electrons must be small size. Carbon atom contains 6 electrons with 6 protons and 6 neutrons in nucleus. Take a construction paper and cut it in circular shape which must be large enough to hold all 18 balls. Now attach 6 balls of protons and 6 balls of neutrons to both sides of the construction paper with the help of craft glue and form a nucleus of the atom.

Now hang the nucleus with the help of thread and a needle and a large knot is tied at the end. The needle has to run through the construction paper top and then the other end of the fishing line is tied to the bottom of a wire clothes hanger. Then the floral wire is bent into a circular shape and all the six small balls are pierced onto one end of the wire. Now spread all electrons evenly to model orbiting electrons and the two ends of the wire together is twisted so that the balls do not loosen up and make into a close circle of orbit.

Question:This is a 5th grade science project. We have googled this a bit but have come up with pretty elaborate and overwhelming projects and sites. She will be doing this on her own and suggestions for websites or materials that a 5th grader can understand and manage are appreciated.

Answers:You need a nucleus with 6 protons and 6 neutrons. Styfofoam balls are good. Protons and neutrons are the same size, but make them dfferent colors. The protons have a + charge. You could write that on them. The neutrons do not have a charge. Mix them up, the protons do not like to be near each other. Surrounding the nucleus you need 2 rings of electrons. There are 2 in the first ring and 4 in the next. Spread them out ,they do not like each other. They have a - charge. They are much smaller than protons. I have seen 3D models done hanging on a coat hanger. The nucleus hanging in the center and the electrons hanging outside of it. Then the whole thing can hang up too.Bend the body of the hanger to a round shape.

Question:i need to build one of these for a school project. ive googled it but didn't fin anything helpful. if you know of any good websites or if u could possibly attach a picture that would be great!! thanks!

Answers:A simplistic model would be 6 protons and 6 neutrons in the middle, with 6 (much smaller) electrons evenly distributed around the outside. http://en.wikipedia.org/wiki/Rutherford_model A slightly more complex model would show the 6 electrons separated into two inner electrons and 4 outer electrons. An even more complicated model would show the 1s, 2s and 2p subshells with the electrons in. Possibly also representing the spin of the electrons somehow, alternatively, show just the 90% probability surfaces for them. Check this page for more details: http://www.uwgb.edu/dutchs/PETROLGY/WhatElmsLookLike.HTM http://en.wikipedia.org/wiki/Atomic_orbital A more complex model again would show all of the quarks that make up the protons and neutrons in the nucleus bound into groups of three (up, up, down for protons, up, down, down for neutrons). http://en.wikipedia.org/wiki/Quarks A yet more complex model would show that each of the three quarks per nucleon have a different colour, red green and blue to match their "colour charge". http://en.wikipedia.org/wiki/Colour_charge

Question:I need to create a 3D model of a Carbon atom with a covalent bond. What does that look like? Pictures/examples will be helpful. Must include protons, neutrons, electrons, and electron shell.

Answers:Carbon atoms have 4 bonds. http://www.chm.bris.ac.uk/pt/harvey/gcse/covalent.html That website has several pictures of 3D carbon covalent bond molecules :)

Question:http://physics.uoregon.edu/~jimbrau/BrauImNew/Chap04/FG04_11.jpg the second picture is that of carbon....i have to make a 3d project for science class is that the right model to follow after if not please give me ideas yeah i have to use pipecleaners and styrophome balls i sont think that picture is gonna worl

Answers:yeah that would be the right model to use. http://www.mbe.doe.gov/me70/manhattan/images/AtomLabeledLarge.gif is one thats more familiar. Are you going to do the styrofoam ball and pipecleaner route or otherwise?
