The last column of the periodic table contains the noble gases elements that do not easily form chemical bonds. Why don’t these gases
tend to form chemical bonds?

its is because the chemicals are very diffraction from each other so which makes it difficult to form a chemical bond.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
