3. I consulted Wikipedia and I couldn't an elemet that melts at 570 deg. F. The closest I came was Thallium at 579 and Astatine at 576 deg F.
5. Propane has a specific gravity of 1.55, but it's a compound, not an element. Calcium is the element with a specific gravity of 1.55.
8. Can't find an element with that boiling point.
13. Sulfur smells like rotten eggs.
14. Probably Zinc. Wikipeda quotes the melting point as 419.53 deg C and the boiling point of 907 deg C.

there is no element that smells like rotten eggs, it is a compound called Hydrogen Sulfide
for number 5 you can eliminate all gasses and metals, the Sp Gr isn't right for them
