Title: electromagnetic radiation
Post by: dot on December 14, 2009, 02:56:38 PM
The bond energy of a carbon-carbon is approximately 350 kJ/mol. Explain why electromagnetic radiation with wavelengths shorter than those in the visible region of the spectrum is often called ionization radiation. Any help is appreciated! Thank you!

Ionizing radiation consists of subatomic particles or electromagnetic waves that are energetic enough to detach electrons from atoms or molecules, ionizing them.
Examples of ionizing particles are energetic alpha particles, beta particles, and neutrons. The ability of an electromagnetic wave (photons) to ionize an atom or molecule depends on its frequency. Radiation on the short-wavelength end of the electromagnetic spectrum — high frequency ultraviolet, x-rays, and gamma rays — is ionizing.
