What is two?
The temperature scale scientists use.
What is Kelvin scale?
The group of elements on the periodic table that can act as both metals and non-metals.
What are the metalloids?
Melting is defined as this type of change.
What is physical change?
The type of bonding that occurs when electrons are transferred.
