Explanation:
Conduction is a form of heat transfer between one body and another. It usually occurs when a warmer object is in contact with a cooler one. Heat generally flows from a region of high temperature to a place at a lower temperature.
- Conduction is very pronounced in solid bodies.
- The heat transfer causes a net transfer of the average kinetic energy of one body to the other.
- Some examples are: heating of iron by a hotter metallic body, the pot hand getting hotter as cooking continues, cooling of ice by touching it.
The atomic radium increases to the left and downwards on the periodic table.
By that logic, Se has the largest radius.
