Calculate the predicted melting point for radioactive technetium,Tc,given the melting points of manganese,Mn, (1244 °C)and rhenium,Re, (3180 °C).

Question

Quizplus · Accepted Answer

The predicted melting point for Tc can be estimated using the linear relationship between the melting points of Mn and Re, which have atomic numbers closest to Tc. The relationship is as follows: 
melting point of Tc = (melting point of Mn + melting point of Re) / 2 
= (1244 °C + 3180 °C) / 2 
= 2212 °C 
Therefore, the best choice is C.
