Mercury Hg - 80. It's 80 degrees outside.
Krypton Kr - 36. The population of Krypton when it exploded was 36 billion.
Xenon Xe - 54. The Warrior Princess Xena is 54 years old.
Radon - Rn 86. We need to 86 (i.e., reject) Radon in our homes.
Plutonium - Pu 94. In '94 is when the first large Kuiper Belt objects were discovered, that would later lead to Pluto's demotion.
Iodine - I - 53. The thyroid is in the neck, about 5 ft 3 inches from the floor, and needs iodine to operate.
Fluorine - F -9. A small tube of fluoride toothpaste will last 9 brushings.
For the rest, and for mass numbers, try a chemistry book. There are also many excellent web sites.

Seriously. It would be so much easier to go to wikipedia, just type in the word, write it down. Actually, it would take you only 5 minutes, unlike WAITING 20 minutes for some answers from people you dont know! We could just make stuff up too.

This information is very easy to find:
http://www.webelements.com/webelements/elements/text/Hg/key.html
Mercury is Hg - 200.59 (2) - 80
Krypton is Kr - 83.798(2) - 36
Xenon is Xe - 131.293(6) - 54
Radon is Rn - [222] - 86
Plutonium is Pu - [244] - 94
Iodine is I - 126.90447(3) - 53
Fluorine is F - 18.9984032(5) - 9

ha we just learned this
Mercury- Hg Atomic #-80 Mass#-200.59
Krypton- Kr Atomic #- 36 Mass#-83.80
Xenon- Xe Atomic #-54 Mass#-131.290
Radon-Rn Atomic-86 mass-222.018
Iodine- I(captal i) Atomic- 53 mass-126.904
Fluorine- F Atomic- 9 Mass- 18.998
u should get a periodic table

Look on the periodic table. This is the best way to do your homework and remember what you have learned rather than have other people to do it for you. This is basically cheating. SO GO SEARCH THE NET OR LOOK ON THE PERIODIC TABLE.
