Unit 1 Section B Summary HW Problems Pt. 3

#11:

a. the farthest right column (Group 18).

b. they are all gases.

c. they are very unreactive

#12:

#13:

#14:

I would expect the boiling point of chlorine to be lower than that of iodine because chorine is placed higher on the column.  Also, since the boiling point of sulfur (S) is lower than the boiling point of tellurium (Te), and sulfur is higher on the column as well, I can assume that the pattern continues and the boiling point is still lower.

#15:
Atoms of metallic elements are more likely to lose an electron.

#16:
a. cation
b. cation
c. anion
d. cation
e. anion
f. cation
g. cation
h. anion

#17:
Noble gases are known to be very unreactive, which explains why they rarely lose or gain an electron.

#18:
a. anion
b. neutral
c. neutral
d. cation
e. cation
