Correct Answer

Explanation

Neutral atoms of neon with atomic number 10 have the same number of electrons as protons. In a neutral atom, the number of electrons is equal to the number of protons in order to maintain an overall electrically neutral charge. The atomic number of an element, such as neon in this case, is equal to the number of protons in its nucleus. Therefore, for neon with atomic number 10, it has 10 electrons and 10 protons in a neutral state.
