Ionic Compounds Flashcards
Metals normally form ions which have a positive charge, while non-metals form ions with a negative charge.
Ions are attracted to other ions with the opposite charge, due to electrostatic forces
Ionic structures involve many ions bonded together via
ionic bonds
The solid arranges itself into a regular 3D structure known as a
lattice
three properties that ionic compounds have:
High melting and boiling points
High strength bonds
Conduct electricity when liquid
Why can ionic compounds only conduct electricity when in liquid/molten, or aqueous form?
In order for a material to conduct electricity, it must have charged particles (like electrons or ions), that are free to flow through the structure.
why is it so hard to break the bonds of an ionic compound?
Ionic compounds have relatively high melting and boiling points.
This is because ionic bonds are very strong, and a high amount of energy is required to break the bonds.
do ionic compounds have charge?
Remember that ionic compounds arrange their ions in a way that creates a neutral overall charge.
do ionic compounds have charge?
no. Remember that ionic compounds arrange their ions in a way that creates a neutral overall charge.
