Metallic Bonding Flashcards
1
Q
Metallic bonding
A
Strong electrostatic attraction between positive metal ions & delocalised sea of electrons
2
Q
How does no.delocalised electrons per atom affect melting point?
A
More = stronger bonding & higher melting point
3
Q
4 properties of metals
A
1) High melting points
2) Good thermal conductors
3) Good electrical conductors
4) Insoluble
4
Q
3 electron pairs, no lone pairs
A
Trigonal planar
5
Q
Ductile
A
Can be pulled into wires
6
Q
Malleable
A
Can be hammered into shape
7
Q
What are high melting points due to? 2 things
A
Giant lattice and strong electrostatic attraction between ions and electrons
