Types of bonding Flashcards
What is an ionic bond?
A bond between a metal and a non metal where electrons are transferred
What is a covalent bond?
A bond between a non metal and a non metal where a pair of electrons are shared
Can an ionic bond conduct electricity when solid, why or why not?
No, because there are no mobile ions to conduct electricity because the ions are in a fixed giant ionic lattice
Can an ionic bond conduct electricity when molten, why or why not?
Yes, because the ions are now mobile and can transfer electricity because the giant ionic lattice has broken down
Can a covalent bond conduct electricity when solid, why or why not?
No, because there are no mobile electrons to conduct electricity because the electrons are shared between the atoms
Can a covalent bond conduct electricity when molten, why or why not?
No, because there are no mobile electrons to conduct electricity because the electrons are shared between the atoms
Can a metallic bond conduct electricity when solid, why or why not?
Yes, because the electrons are mobile and can move between the metallic ions to conduct electricity
Can a metallic bond conduct electricity when molten, why or why not?
Yes, because the electrons are mobile and can move between the metallic ions to conduct electricity
Do ionic bonded substances have a high or low melting point, why or why not?
Ionic bonded substances have a high melting point because the electrostatic attraction between the oppositely charged ions is very strong so a lot of energy is needed to break them
Do covalently bonded substances have a high or low melting point, why or why not?
Covalently bonded substances have low melting points because the intermolecular forces between the molecules are weak, not much energy is needed to break them.
Do metallically bonded substances have a high or low melting point, why or why not?
Metallically bonded substances have a high melting point because the there are many electrostatic attraction bonds between the oppositely charged ions which are very strong so a lot of energy is needed to break them
How is an ionic compound structured?
In a giant lattice structure
How is a covalent compound structured?
In a simple molecule or a lattice structure
How is a metallic compound structured?
In a giant lattice structure
