Step 1:: Identify what positive ions and neutral atoms are.
A neutral atom is an atom that has an equal number of protons and electrons. A positive ion, on the other hand, is an atom that has lost one or more electrons, resulting in a net positive charge.
Step 2:: Analyze the given options.
Option A: Positive ions have lost protons. This statement is incorrect because the loss of protons would result in a different element formation, not a positive ion. Option B: Positive ions have gained protons. This statement is incorrect because gaining protons would result in a different element formation, not a positive ion. Option C: Positive ions have lost electrons. This statement is correct. Positive ions are formed when atoms lose one or more electrons. Option D: Positive ions have gained electrons. This statement is incorrect because gaining electrons would result in a negative charge, not a positive one.
Step 3:: Select the correct answer.
Final Answer
The correct answer is option C: Positive ions have lost electrons.
