how do i make a ionic bond model?

Question

im a 8th grader and i know what is aionic bond ijust dont know how to make it as a model. does anybody know? im using marshmellows and toothpicks.

Answer 1

lets see with iron and oxigen

Fe 3+ O 2-

Fe2O3

.......O
........|
O -- Fe -- O

the lines are thoopics, and the O and Fe are the marshmellows.

Answer 2

Ionic Bond Model

Answer 3

You need to make two models, one depicting the condition of the atoms before creation of the ionic bond and one to show the condition of the atoms afterward. The reason is that in an ionic bond, one atom "steals" one or more electrons.

Just to keep things simple, use something where only one electron is "stolen". Sodium chloride is a common example.

Prior to the creation of the bond, sodium has an electron all alone in its outer orbital. Poor lonely electron. Chlorine, on the other hand, has 7 electrons in its outer orbital, but would be really happy if it could have 8. Big party going on there, but somebody doesn't have a date.

The sodium atom gets close to the chlorine atom and the lonely electron sees the big party and wants to be part of it. Chlorine says, "hey, come on over!" So the lonely electron from the sodium atom jumps ship over to the chlorine, which causes it to have a net negative charge. The sodium atom, which has lost an electron, ends up with a net positive charge.

The electrical attraction between the positive sodium ion and the negative chlorine ion keep them close together, but electrical forces are pretty weak and the two can be separated easily, making ionic bonds quite weak.

I kinda digressed there, but back to the beginning, I suggest that you build a model that shows the sodium and chlorine atoms in their "normal" state and then a second model that shows their appearance after chlorine has stolen the electron.
