Because radium is a metal.
The radioactive element radium is a pretty good conductor of thermal and electrical energy. We see radium at the bottom of the Group 2 elements, the Alkaline Earth Metals. It can conduct heat and electricity well.
Yes plants are the very good conductors of heat.
Radium is radioactive and lead is a good radiation shield.
Samarium is a good conductor for heat and electricity.
Because radium is a metal.
A good insulator means a bad conductor. It is the opposite of good conductor.
zinc is a good conductor of electricity
Water is a good conductor of heat.
Being a metal, it is a good conductor.
Why is glass a good conductor of heat and ceramic is not a good conductor of heat?
your skin
No, it's a good conductor.
No, it's a good conductor.
No. Ceramic is a bad conductor of heat and electricity.
Glass is a poor conductor of heat.
No. Copper is a good conductor of heat.
