How do I make a model of the atom MgCl2? It has to be bigger than a shoe box. I dont know how to make it.?

Question

It is for a science project. I was think of using styrofoam balls. How do i put it all together, (like how many protons, electrons, neutrons) to put in it. So if anyone has any ideas they would help!

Thanks

Answer 1

Mg will be in the middle. It has 12 protons, 12 neutrons, and 12 electrons. A Cl will be on each end to form a line. Cl has 17 protons, 18 neutrons, and 17 electrons.

These atoms actually form ions when they react. To make you MgCl2 reaalistic you need to take two electrons from the Mg. This leaves the Mg with only 10 electrons and a 2+ charge. Give one of Mg's electrons to each Cl. Now each Cl will have 18 electrons. Give each Cl a 1- charge.

The Mg 2+ will hold a Cl 1- on each end to form a linear shape.
