Suggest one change you could make to this diagram, to better reflect the scale of the sub-atomic particles.
Imagine that a new element called MYPium had been isolated. It has low density, and is a solid which is soft and easily cut with a knife. It is extremely reactive with both air and water. It is a good conductor of heat and electricity, and also has a low melting point. Interpret this information to judge:
In which group in the periodic table would you place MYPium?
