Which element(s) would you expect to behave similarly to Gadolinium? What properties of would you expect to be the same, what would be different?

distance, luminosity, brightness, radius, chemical composition, and temperature

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the answers would be

the first one and the second one
