First, we need to determine the number of core electrons in chlorine (Cl). Chlorine is in the 3rd period and 17th group of the periodic table, which means it has 17 electrons in total. The core electrons are those in the inner shells, not the valence electrons. Chlorine has 2 shells before its valence shell, with 2 electrons in the first shell and 8 in the second, giving us a total of 10 core electrons.

Now, we need to find an element with a total of 10 electrons. Looking at the options:

A. Neon (Ne) has 10 electrons.
B. Argon (Ar) has 18 electrons.
C. Sodium (Na) has 11 electrons.
D. Fluorine (Fe) is incorrect. The symbol for Fluorine is F, not Fe. Fluorine has 9 electrons.

So, the correct answer is A. Neon (Ne), which has a total of 10 electrons, equal to the number of core electrons in chlorine (Cl).
