Answer:
B) Chlorine
Explanation:
In your case, the sulfide anion, S2− , carries a (2−) negative charge, which can only mean that it gained electrons. More specifically, it gained 2 electrons. A neutral sulfur atom has an atomic number equal to 16 , which means that it has 16 protons inside its nucleus and 16 electrons surrounding its nucleus.
Why its not Magnesium? Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column of the periodic .
Its not Lithium because Lithium's atomic number is 3, therefore Lithium is not equal to S2 atomic number 16.
Why is it not Helium? Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.
Chlorine is the closest to S2 atomic number 16,Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature
