Solution
Solution Steps
Step 1: Understanding the Definition of an Ion
An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons. This means that the number of protons (positively charged) and electrons (negatively charged) are not equal.
Step 2: Identifying the Relevant Particles
The question asks about the particles that need to be unequal for an atom to be considered an ion. The relevant particles in this context are protons and electrons.
Step 3: Analyzing the Options
Protons and neutrons: The number of protons and neutrons being unequal does not make an atom an ion; it affects the isotope of the element.
Electrons and neutrons: The number of electrons and neutrons being unequal is not relevant to the definition of an ion.
Protons and electrons: An atom becomes an ion when the number of protons and electrons are unequal.
