Bonding Flashcards
1
Q
Define Ionic bonding.
A
The electrostatic force of attraction between oppositely charged ions formed by electron transfer.
2
Q
Define metallic bonding.
A
The electrostatic force of attraction between the positive metal ions and the delocalised electrons.
3
Q
Define a covalent bond.
A
A shared pair of electrons.
4
Q
What does a dative/co-ordinate covalent bond mean?
A
The shared pair of electrons come from only one of the bonding atoms.
5
Q
Do metal atoms gain or lose electrons and do they form +ve or -ve ions?
A
Lose electrons and +ve ions.
6
Q
Do non-metal atoms gain or lose electrons and do they form +ve or -ve ions?
A
Gain electrons and -ve ions.
7
Q
What affects how strong the metallic bonding is?
A
- Number of protons- more=stronger.
- Number of delocalised electrons- more=stronger.
- The size of the ion- smaller=stronger
