Chapter 4.5 Flashcards
1
Q
Metallic structure
A
Regular lattice arrangement of positive ions surrounded by a sea of delocalized electrons
2
Q
Metallic bonding
A
The electrostatic attraction between the positive ions in the lattice and the delocalized electrons
3
Q
Alloy
A
Homogeneous mixtures of two or more metals, or of a metal with a non-metal
4
Q
Why are metals malleable/ductile?
A
Bonding is non-directional, so when layers slide over each other the structure is the same unlike ionic solids where like charges repel
