(3) probably astatine. it melts at 302°C, or 575°F
(5) calcium
(8) probably cobalt. it melts at 1495°C and boils at 2870°C.
(13) none that I know of. Hydrogen sulfide and certain organic compounds of sulfur smell like rotten eggs. Sulfur itself kind of smell like match tips.
(14) zinc comes within 1 degree of those numbers you listed.

Zinc boils at 907C... Cobalt melts at 1494C. Hope this helps. I also think sulfur smells like rotten eggs.

plant life have 2 systems that animal cells have not got: cellular partitions, and chloroplasts besides the shown fact that, cellular partitions encompass the cellular membrane, and chloroplasts are in the cellular. This shape is used in the technique of photosynthesis to help in making "food" for the plant to apply. Animal cells do no longer choose this shape, as they're purchasers.
