Technetium's Atomic number is 43.The
Atomic mass is 74 and the symbol is Tc. This has 43 numbers of Protons and 43
numbers of Neutrons and 43 Electrons. The melting point is 2430k and 3915
0 F. The boiling point is 4538k and 7709 0 F. The
phase is a solid and this product is illegal here so there is no cost. This element belongs in the transition family. This was discovered by Carol Perrier and Emilio Segre.
