Thermal Conductivity: ability of a material to conduct heat. Measured in (DTU/(m*s))/°C. Heat transfer occurs at a lower rate in materials of low thermal conductivity (better insulaton) than in materials of high thermal conductivity (better conductivity).

Specific Heat Capacity: value, measured in (DTU/g)/°C, required to heat 1 g of the selected object by 1 °K. Elements with higher value of Specific Heat Capacity require more energy to increase their temperature.

Molar Mass: the mass of a given substance divided by the amount of substance. Elements with a lower value of molar mass are lighter.

Hardness: how is difficult excavate a solid material.

Temp: temperature (in Celsius) at which an element transitions toState and toElement.
