Ionic Compounds Flashcards
What is an ionic compound?
A compound made up of one or more positive metal ions (cations) and one or more negative non-metal ions (anions)
What type of structure do ionic compounds form?
Ionic compounds can join together in the form of a crystal structure.
What bond are ions held in an ionic compound?
An ionic bond
What is an ionic bond?
The simultaneous strong attraction of positive and negative ions in an ionic compound
What are three conclusions that can be made about ionic compounds?
- they conduct electricity
- they have relatively high melting points
- they are soluble (dissolve easy)
What is an electrolyte?
An ionic compound that dissolves and creates a solution that conducts electricity.
How do you name an ionic compound?
Name the metal element first.
Add the name of the non-metal with the ending changed to “ide” after.
Sodium + Chlorine = Sodium Chloride
What is a polyatomic ion?
An ion that is made up of more than one atom that acts as a single particle.
How do you name a polyatomic ion?
The name of the metal first.
The name of the polyatomic ion goes second.
Sodium Carbonate
What metals can have more than one possible ionic charge?
Transition Metals
How do you include the charge of a transition metal in the name of an ionic compound?
You put the charge in Roman numerals in brackets.
Iron (lll)
