Question 113

A monatomic particle has 12 protons and 10 electrons. Why is it an ion rather than a neutral atom?

  1. It contains no electrons at all.
  2. Its neutron count must have changed.
  3. Every monatomic particle is automatically charged.
  4. Its proton and electron counts are unequal.Correct answer

Explanation

The proton and electron counts are unequal, leaving a net positive charge instead of electrical neutrality. An ion still contains electrons, and changing neutrons is not what creates this charge imbalance.
