Its nuclear flesh is 78 and its mass is 195.08. It is also one of the heaviest metals. It is a transit metal and its electron configuration is [Xe ]6s14f145d9. This element has genuinely erratic properties, which make it valuable. First of all, it is very easily shaped. It push deflection be shaped and working into almost every accomplishable way, from thin wire too large sheets. Platinum is a solid who?s melting localise is 2045k and its boiling charge is 4100k.
The metal was used by pre-Columbian Indians. Platinum occurs native, attach to by small quantities of iridium, osmium, palladium, ruthenium, and rhodium. These all belong to the same friendship of metals. The metal does not oxidize in air at any temperature. However, halogens, cyanides, sulfur, and caustic alkalis corrode it.
