Question 120

A stable atom is ionized by removing an electron. Which statement correctly separates ionization from nuclear radioactivity?

  1. Ionization alone does not make the nucleus radioactive.Correct answer
  2. Every ion is radioactive.
  3. Electron removal always changes the nucleus.
  4. Only neutral atoms can have stable nuclei.

Explanation

Removing an electron changes the atom's charge but does not by itself destabilize or transform the nucleus. Assuming every charged atom is radioactive confuses an electron-shell change with a nuclear process.
