Physical Change

Atoms are a substance are not rearranged, but the substance is in a different state of matter

Iron (Fe)

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

Which of the metals are the MOST reactive??

Alkali Metals

Which of the metals are the LEAST reactive?
