200
do not conduct heat or electricity, typically brittle and are not easily molded into shapes.
What are non-metals?
200
neutrons are found outside the nucleus of an atom

What is bonding?
400
elements are arranged by their atomic mass number
What is false (atomic number also the number of protons)
400
