Which term best matches 'the process by which electrons are removed from atoms'?

• A. Ionization.
• B. Intensity.
• C. Kilovoltage.
• D. Latent period.

Answer: (A)

Removing electrons from atoms is called ionization. This happens when enough energy is provided to overcome the attraction of the nucleus, so an electron is ejected and the atom becomes a positively charged ion. In radiation contexts, ionization is the key way matter becomes charged as radiation interacts with it. The other terms don’t describe this action: intensity talks about how much energy passes through a area but not about removing electrons; kilovoltage is a measure of electric potential that can drive electrons but isn’t the act of removal itself; latent period refers to a delay before an effect occurs, not the actual loss of electrons.
