one proton, zero neutrons, two electrons \tone proton, zero neutrons, one electron \tone proton, zero neutrons, zero electrons
two protons, one neutron, two electrons
three protons, three neutrons, two electrons
three protons, three neutrons, three electrons

Explanation:

To solve this, we use the definitions:

• Neutral atom: Protons (\(p^+\)) = Electrons (\(e^-\))
• Positive ion: \(p^+ > e^-\) (lost electrons)
• Negative ion: \(p^+ < e^-\) (gained electrons)

Analyze each phrase:

1. one proton, zero neutrons, two electrons

\(p^+ = 1\), \(e^- = 2\). Since \(1 < 2\), this is a Negative ion.

1. one proton, zero neutrons, one electron

\(p^+ = 1\), \(e^- = 1\). Since \(1 = 1\), this is a Neutral atom.

1. one proton, zero neutrons, zero electrons

\(p^+ = 1\), \(e^- = 0\). Since \(1 > 0\), this is a Positive ion.

1. two protons, one neutron, two electrons

\(p^+ = 2\), \(e^- = 2\). Since \(2 = 2\), this is a Neutral atom.

1. three protons, three neutrons, two electrons

\(p^+ = 3\), \(e^- = 2\). Since \(3 > 2\), this is a Positive ion.

1. three protons, three neutrons, three electrons

\(p^+ = 3\), \(e^- = 3\). Since \(3 = 3\), this is a Neutral atom.

Final Categorization:

• Positive ion:
• one proton, zero neutrons, zero electrons
• three protons, three neutrons, two electrons

• Negative ion:
• one proton, zero neutrons, two electrons

• Neutral atom:
• one proton, zero neutrons, one electron
• two protons, one neutron, two electrons
• three protons, three neutrons, three electrons

(If you need to drag-and-drop, assign each phrase to the correct category using the above logic.)
