How do physical and chemical properties differ from physical and chemical changes?
Properties are the ability to do and changes are actually doing it.
Define BOTH homogeneous mixture and heterogeneous mixture.
A homogeneous mixture is the same throughout.
A heterogeneous mixture you can see the different parts.
Which family does the trend electronegativity NOT apply to?
The noble gas family
