Bonding And Structure Flashcards
1
Q
What types of bonding exist between atoms ?
A
Ionic, Covalent and Metallic bonding
2
Q
Why do ionic compounds have high melting and boiling points ?
A
Strong electrostatic forces of attraction (between oppositely charged ions) requires a lot of energy to overcome
3
Q
What is a covalent bond ?
A
A shared pair of electrons between two non-metal atoms
4
Q
What is the structure of diamond ?
A
A giant covalent structure where each carbon atom is covalently bonded to four others
5
Q
Why do metals conduct electricity ?
A
They have delocalised electrons that can move freely
6
Q
What happens to particles during melting ?
A
They gain energy, overcome some forces of attraction and move more freely
