Metalic Solids Flashcards
Type of particles
Atoms (Metalic)
In a 3D lattice structure surrounded by some free moving valence electrons.
Attractive forces
Metallic bonding
Held together by the attraction between the free valence electrons from neighbouring atoms.
Melting point
Very high, lots of energy is required to break most types of metallic bonds.
Are metals hard and strong?
Yes, due to strong metallic bonding.
Can a metal be deformed?
Yes, as it is non-directional.
Layers of metallic atoms can slide past one another breaking metal’s structure.
Malleable
Are metals soluble in any solvent?
No, they are not broken by the attraction of solvent molecules.
Do metals conduct electricity?
Yes, a large number of valence electrons free to move around in the structure.
The lower the resistance the better conductivity of the metal.
