Help Query the physical property parameters of three elements Ge,Ti,Au?

Properties of Ti: Group 4 (ⅣB) element, atomic number 22, stable isotopes 46,47,48,49,50, density 4,47,48,49,50. Atomic number 22, stable isotopes 46,47,48,49,50, density 4,54g/cm3, melting point (1660±10)℃, boiling point 3287℃. Boiling point 3287℃. Main oxidation state +3,+4. silver-gray metal. Silver gray metal. Surface can form a dense inert oxide film. Also has the properties of low density, high specific strength, high and low temperature corrosion resistance and biophilicity. Does not react with dilute hydrochloric acid, sulfuric acid and nitric acid at room temperature. When heated, it can react with oxygen, nitrogen, sulfur and halogens and other non-metals. It can form alloys with most metals and some non-metals. The main titanium ores are ilmenite and rutile. Titanium metal can be produced by reducing titanium tetrachloride with magnesium. The more successful method is electrolysis with TICl4 as the raw material and NaCl or NaCl-KCl as the solvent electrolyte system. Mainly used in the manufacture of space shuttles, rockets and missiles, submarines, chemical equipment, medical equipment, artificial joints and so on. It is also used to make titanium dioxide.
