Ionic Bonding Flashcards
When does ionic bonding occur?
Between a metal and a non-metal.
What happens to the electrons?
They are transferred from one atom to another to form electrically charged ions
What happens to atoms that lose electrons?
They become positively charged ions
What happens to atoms that gain electrons?
They become negatively charged ions
What does each ion have?
A full or empty outer shells of electrons
What is an example of ionic compounds (salts)?
Compounds of Group 1 and Group 7 elements
What do ionic compounds form?
Crystals because the ions are arranged into a regular lattice.
What happens when ionic crystals melt or dissolve in water?
They conduct electricity
Why do ionic compounds conduct electricity when they’re molten or dissolved in water?
Because the charged ions are free to move around
