A:
Yup, a solid piece of titanium should sink nicely in water. Titanium, according to my periodic table, has an average density of 4.51 grams per milliliter, as compared to water's 1 g/ml, so it's 4.5 times as dense.

You can make a little boat out of titanium and it should float, but that's because you're really averaging in all the air in there.
