• D. 8

Answer: (A)

Verified step by step guidance

1. Recall that the number of protons in an atom is equal to its atomic number, which uniquely identifies the element.
2. Look up the atomic number of neon (Ne) on the periodic table; this number represents the number of protons in a neutral neon atom.
3. Understand that a neutral atom has an equal number of protons and electrons, but the question only asks for protons.
4. Note that neon's atomic number is 10, meaning it has 10 protons in its nucleus.
5. Therefore, the number of protons in a neutral neon atom is equal to its atomic number, which is 10.
