Metallic bonding Flashcards
1
Q
Describe metallic bonding
A
the lattice of positive ions in a sea of delocalized electrons
2
Q
Describe the structure of a typical metal
A
In a metal, each negatively charged electron are joined with a positively charged ion
3
Q
State the properties of a typical metal
A
- They conduct electricity because there are free electrons to carry charges
- Malleable, they are arranged in a pattern of layers that slide over each other when force is applied
- Hard, because the atoms are close together due to the metallic bonds
- High melting point because the electrostatic forces between the positive ions and the negative electrons are strong
