what neutral atom has the same number of electrons as the sulfur anion s²⁻?
○ cl
○ ne
○ ar
○ p

Explanation:

Step1: Find sulfur's atomic number

Sulfur (S) has an atomic number of 16. In a neutral sulfur atom, the number of electrons is equal to the atomic number, so a neutral S - atom has 16 electrons.

Step2: Determine electrons in $S^{2 - }$

The $S^{2 - }$ anion has gained 2 electrons. So the number of electrons in $S^{2 - }$ is $16 + 2=18$ electrons.

Step3: Identify the neutral atom with 18 electrons

The atomic number of an atom is equal to the number of electrons in a neutral atom. The element with an atomic number of 18 is Argon (Ar).

Answer:

C. Ar
