how to make a model of a molecules?

Question

the model should be a ball and stick model

please include what web site can i find the answer

Answer 1

Some teaching and education outlets may have ball and stick models (or stickball and tubing) you can use. Each of the elements will have only so many potential bonds, so premade ones will have the spacing and number of holes/angles correct. Complex organic molecules will be less tedious to build with the new materials.

If you can't get those, and this is for basic homeschooling, then perhaps you can utilize some craft shops may have styrofoam pieces (which are used for making dolls, snowmen, tree ornaments) and some sort of sticks you can use. This will make it a bit harder since the regular spacing between bonds may be harder to do. With double bonds, I guess you have to use something flexible, like pipe cleaners, lol. I'd probably only improvise for the simplest molecules.

Answer 2

i do make my own ball-and-stick molecule models since it is quite expensive ordering from USA. what i do is use clay (different colors for the atoms), pipe cleaners, paintbrush and glue.

mold the clay into your desired size. just make approximations of what size for each atom such as O, C, Na, Cl, etc. use the pipe cleaners as your bond. this is easy to use since it is flexible and cheap. dip the paintbrush in the glue and dab some glue in the ball so it would look shiny and wont get molds at all.

Answer 3

Cotton balls and toothpicks. The model should be fuzzy, rather than solid, because matter at the atomic level really isn't solid, but fuzzy, in a quantum sort of way.

Answer 4

I always liked the colored giant marshmallow (colors determine the element) and painted wooden skewer trick. (One color for stong bonds and another for weak)
Try sucrose or glucose, really fun!
When you are done with the display, light up the bunsen burners and make s'mores!
