The density is a physical property not a change.
No. Titanium (4.43 g/cc) is naturally less dense than iron (7.87 g/cc).
That is not a chemical property. It is a physical property since density can be observed without changing the chemistry of the elements, thus it is a physical property.
LCB titanium contain: molybdenum-6,8 %, iron-4,5 %, aluminium-1,5 %.
The process of iron rusting is a chemical change.
Chemical, as rust is iron oxide. The iron is turning from iron to iron oxide, which (as you can see) is a chemical change. In general, a colour change usually indicates a chemical change.
I think it`s a chemical change.

Chemical formula iron titanium oxide, FeTiO3
I list them in order of heaviest to lightest:Gold, Silver, Iron, Titanium. Gold has no ore and ores are always less dense than the metal.
LCB titanium contain: molybdenum-6,8 %, iron-4,5 %, aluminium-1,5 %.
