Explanation:

Step1: Recall atomic numbers (protons)

• Neon (Ne): Atomic number 10 (10 protons).
• Magnesium (Mg): Atomic number 12 (12 protons).
• Silver (Ag): Atomic number 47 (47 protons).
• Plutonium (Pu): Atomic number 94 (94 protons).

Step2: Order from lowest to highest

Arrange by increasing atomic number (protons): Neon (10) < Magnesium (12) < Silver (47) < Plutonium (94).

Answer:

Top (lowest protons): neon
Next: magnesium
Next: silver
Bottom (highest protons): plutonium

(Order: neon, magnesium, silver, plutonium)
