Write down five properties of metals.
Answers
High ductility / tensile strength - eg. Wire drawing
High malleability - eg. Forging or rolling
Elastic and plastic deformation
High fracture toughness above the Brittle-Ductile transition temperature
High electrical conductivity
Most metals reflect light of all wavelengths equally well so look white or nearly so and shiny
Metals are transparent to gamma rays and to short wavelength X-rays
High thermal conductivity
Low Specific heat capacity
Most metals have some paramagnetism
Most metals have high densities and very high melting points
Most metals have low 1st ionisation energies and Work functions
Most metals exist in nature as their oxides
Most metals are alloy forming
or else it can also be
Though this subject is more related to a solid state physicists.But from my undergraduate courses in solid states physics (1964)I can write the following main properties:
1-If you polish it it looks shiny and silvary looking
2- its structure is closely backed.
3-its ionisation energy is low
4-It is naturlly in combined states
5-It is a good conductor of thermal(heat) and electricity
6-It has at least one basic oxide
7- It has the character of making alloys with other matel
Answer:
- Good electric and heat conductor
- opaque as a thin sheet
- solid at room temperature (except Hg)
- possess metallic luster
- can able to stretched into wire.
