What happens to the electrons of metals and non-metals when they react?

Electrons are transferred from the metal to the non-metal.


Why do electrons transfer from a metal to a non-metal during a chemical reaction?

So they both achieve more stable electronic structures


What happens to metals and non-metals when the electron is transferred?

The metals become positive ions
The non-metals become negative ions


What is an ionic compound?

The finished products after electrons transfer from 1 element to another during a chemical reaction


How do you show an ionic compound on an electron diagram?

You draw the 2 ions, with 1 electron transferred. Make sure the electron transferred still has the same symbol as it was in the previous element, as it did not change at all.


How are the ions in an ionic compound arranged?

In a regular way


What is the regular arrangement of ions in an ionic compound called?

A giant ionic lattice


How are the ions in an ionic compound held together?

By ionic bonds


Which directions do ionic bonds act in?

All directions


What are ionic bonds?

They are strong electrostatic forces of of attraction between positively charged ions


What model is appropriate for drawing a giant ionic lattice?

Space-filling model
