Covalent, Ionic, Metallic bonding Flashcards
0
Q
Ionic Compound Properties
A
High melting points
often soluble in water
conduct electricity in water
lattice
1
Q
Ionic Bonds
A
Transfer electrons
2
Q
Why do ionic compounds have high melting points
A
- opposite charges attract, this forms strong ionic bonds
- lots of energy is needed to separate the ions
3
Q
Electrical Conductivity in Ionic Compounds
A
- cant conduct when solid
- ions are tightly held in place
- cant carry charges
- can in molten state
- crystal lattice has broken down and the ions can move
4
Q
Metallic Bonding Properties
A
- High melting point
- high boiling point
Can conduct electricity and heat - hard and dense
- malleable
- ductile
5
Q
Metal Atoms
A
- held together in a sea of delocalised electrons
- each metal gives up electrons into the sea of electrons
