The stable ion the sulfur would form is the sulfide ion,
S
2
−
.
Explanation:
A neutral sulfur atom contains 16 electrons. We can know this because its atomic number is 16, which means there are 16 protons in the nucleus. Since the negative charge of the electrons cancels the charge of the protons, the sulfur atom is neutral. The electron configuration of sulfur is

. The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of

Answer:
D) 7.5 grams
Explanation:
Hello,
In this case, since the percent yield is defined by:
In such a way, since the percent yield is up to 25% and the expected or theoretical amount is 30 g of the product, the actual yield of the reaction is:
Therefore the answer is D) 7.5 grams.
Best regards.
Yes, an explanation/ theory for a phenomena in science is not something that is set in stone. If experiments are done that prove the current explanation is false and this is peer checked, then the explanation can absolutely be proven false.
