C2.2.4 - Ionic Compounds Flashcards
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
