platinum Antonio de Ulloa discovered platinum in South the States in 1735 and by Wood in 1741. Platinum is a silver-white alloy that holds even more value then gold. Its nuclear egress is 78 and its mass is 195.08. It is also one of the heaviest metals. It is a renewing metal and its electron configuration is [Xe ]6s14f145d9. This element has genuinely uncomparable properties, which make it valuable. First of all, it is very easily shaped. It push divagation be shaped and working into almost every realizable way, from thin wire too large sheets. Platinum is a solid who?s melting localise is 2045k and its boiling stopover is 4100k.
