How many electron volts is 1 keV equivalent to?

  1. 100 eV

  2. 1000 eV

  3. 10000 eV

  4. 100000 eV

The correct answer is: 1000 eV

One kiloelectron volt (keV) is defined as equivalent to 1,000 electron volts (eV). In the context of atomic and subatomic physics, these units are commonly used to express the energy of particles or photons. The prefix "kilo-" indicates a factor of 1,000, so when converting keV to eV, you simply multiply by 1,000. Therefore, when asked how many electron volts 1 keV is equivalent to, the correct response is indeed 1,000 eV, aligning perfectly with the accepted definitions and conversions in the field of radiation safety and particle physics.
