Which ionization process requires the most energy? which ionization process requires the most energy? f(g) → f +(g) + e- o(g) → o +(g) + e- f +(g) → f 2+(g) + e- o +(g) → o 2+(g) + e-?

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.
