Lustrous, solid at room tempertaure (except Mercury), conductors and malleable.
What does “ductile” mean?
Metal that is able to be stretched into a wire.
What does “malleable” mean?
Metal that is able to be bent or hammered.
What does “brittle” mean?
Metal that is able to break or crumble.
Why do metallic elements bend, while solid and non-metallic elements break or crumble?
The atoms in a metal are malleable, therefore, can be bent and squashed, while non-metals cannot.
