1. Which of the elements examined should be considered as non-metals?

Any element that doesn’t show all characteristics of a metal isn’t a metal. In other words, if it has metallic luster, and is malleable, but doesn’t conduct electricity, it isn’t a metal

2. The "stairs" on the periodic table divide the metals from the non-metals.

Would you expect Phosphorous to bend without breaking? If it is a metal it should, otherwise it shouldn’t

Would you expect Uranium to bend without breaking? __________________________

Would you expect Bromine conduct electricity? ________________________________

Would you expect Strontium to conduct electricity?____________________________

3. Why do metals feel colder than everything else in the room? _______________________

_______________________________________________________________________

4. Which of the elements that you tested has the …?

Highest ionization energy? Carbon (look at values on back side of periodic table, this element doesn’t quite fit the pattern)

Lowest ionization energy? _________________

Largest radius? ________________

Smallest radius? ________________
