I am in year 8 and have a piece of home I do not understand the question is :
new material has been discovered i the outback of Australia. The material is solid and a dull black colour. Scratching with a diamond cutting blade leaves silver -coloured scratches. When hammeered the material does not crack but maybe dented if hit particularly hard. Attaching crocadile clips to the material shows that an electric current can flow through it. When picked up in the labatory the material feels cold to the touch.
Is this new material a metal or a non metal.
I think that it is a metal but I'm not sure. I have to list as many reasons why I think it is a metal or a non metal.
Thank you.
