Ductility

It is the property of a metal that can be drawn into wire. 

Malleability

The ability of metal that can be beaten into thin sheets is called malleability.

Gold and silver are the most malleable and ductile metals
All metals are solid at room temperature with the exception of mercury (Hg), which is a liquid.

Good conductors of electricity because they have low resistance.


Exception: Titanium, it is a poor conductor of heat and electricity ]]> 2021-08-10 03:10:39 UTC https://padlet.com/kasshvi29saxena/ewro4uxapzj2s7bn/wish/1673622552 LUSTRE BY SHREYA shreya_chaturvedi https://padlet.com/kasshvi29saxena/ewro4uxapzj2s7bn/wish/1673623814 Metals are generally physically lustrous. They have a shiny appearance.
Exception : Lead, which has a dull lustre.]]> 2021-08-10 03:12:02 UTC https://padlet.com/kasshvi29saxena/ewro4uxapzj2s7bn/wish/1673623814 HIGH MELTING AND BOILING POINTS BY SHREYA shreya_chaturvedi https://padlet.com/kasshvi29saxena/ewro4uxapzj2s7bn/wish/1673629978 Metals have high melting points and high boiling points as they have strong metallic bonds.
However, Sodium (Na) and Potassium (K) have low melting and boiling points.

These vibrations from metal ions release energy and this is how a metal is a good conductor of heat.]]> 2021-08-11 06:34:41 UTC https://padlet.com/kasshvi29saxena/ewro4uxapzj2s7bn/wish/1675117637
