C1: Quiz 15
1)
a) Do noble gases have full outer electron shells?
b)
i) How many electrons does helium have in its outermost electron shell?
ii) How many electrons do all of the other noble gases have in their outermost electron shells? The other noble gases are neon, argon, krypton etc…
2) Are the noble gases reactive or unreactive (inert)? Explain your answer.
3) Are the noble gases flammable; yes or no? You don’t need to explain your answer.
4) Group 0 elements are monatomic; what does monatomic mean?
5) The next question is about the characteristics of the group 0 elements.
a) As we go down the periodic table for the group 0 elements, what happens to the melting and boiling points? Explain your answer.
b) As we go down the periodic table for the group 0 elements, what happens to the densities? You do not need to explain your answer.
The next few questions will ask us to predict the characteristics of certain group 0 elements. Here are the group 0 elements in the periodic table.

6) The boiling point of neon is -246°C and the boiling point of krypton is -152°C. Predict the boiling point of argon.
7) Krypton has a density of 0.0037 g/cm3 and radon has a density of 0.0097 g/cm3. Predict the density of xenon.
8) Argon is a gas at -150°C. Predict whether helium will be a gas at -150°C. Explain your answer.
