2 a metal is ductile

3 a metal is opaque

4 a metal is brittle​

4. A metal is brittle

Explanation:

The term 'brittle' means “hard but liable to break easily”. If a material is brittle, it means that when it is subjected to stress, it breaks with little elastic deformation and without significant plastic deformation. ... Metals are not generally brittle. Rather, they are malleable and ductile.
