Ionic Bonding Flashcards
What happens when Lithium bonds with Chlorine?
One electron transferred from Lithium to Chlorine
Why do Atoms transfer Electrons in Ionic bonding?
So they can have Full Outer Shells
What happens when Lithium bonds with Fluorine?
1 Electron transferred from Lithium to Fluorine
What happens when Magnesium bonds with Oxygen?
2 Electrons transferred from Magnesium to Oxygen
What happens when Beryllium bonds with Oxygen?
2 Electrons transferred from Beryllium to Oxygen
What happens when Magnesium bonds with Chlorine?
2 Electrons transferred from 1 Magnesium Atom each going to a different Chlorine Atom
What happens when Sodium bonds with Oxygen?
2 Electrons transferred from 2 Sodium Atoms to an Oxygen Atom
Why do Sodium Ions and Chloride Ions form an Ionic Bond?
Electrostatic Force between the oppositely charged Ions
Why don’t Sulphur Ions and Oxygen Ions form an Ionic Bond?
Both have Negative charges so would Repel
What is the name of a substance made of billions of oppositely charged Ions joined together?
Giant Ionic Lattice
What is a Giant Ionic Lattice
A huge 3D network of Ions
State the mpt of Ionic Substances
High
Why do Ionic Substances have high mpt’s?
Strong Bonds between oppositely charged Ions are hard to break
Will NaCl (s) conduct electricity?
No
Will NaCl (aq) conduct electricity?
Yes
Will NaCl (l) conduct electricity?
Yes
What does Molten mean?
Melted
Why don’t Ionic Compounds conduct electricity when Solid?
Because the Ions aren’t free to move
Why do Ionic Compounds conduct electricity in Solution?
Because the Ions are free to move
Why do Ionic Compounds conduct electricity when Molten?
Because the Ions are free to move
What does Soluble mean?
Dissolves in Water
What does Insoluble mean?
Doesn’t dissolve in Water
What do you need to do to Magnesium Carbonate to make it conduct Electricity?
Melt it
What is the easiest way for Sodium Fluoride to conduct Electricity?
Dissolve it in water because it doesn’t require high temperatures
