I am hard but brittle, and covered in crystals. It takes a while for me to get hot, but I dissolve well in water. I love electricity as well. What am I?
Ionic Substance
I can be all forms of matter, but I get hot really easily. I do not usually dissolve in water well, and I hate electricity. What am I?
Covalent Substance
I am shiny and malleable, and I am solid at room temperature (except for one of us). I am ductile, and I also love electricity. What am I?
A Metal
I can be a solid, liquid, or gas at room temperature, but I am not malleable or ductile. I hate electricity. What am I?
A Non-metal
I can be physically like one of my friends, but sometimes I like electricity like my other friend. Therefore, sometimes I’m called a semi-conductor. What am I?
A Metalloid
