Question

Unknown element X is a metal that ionically bonds to sulfur.

Is the formula, X3S feasible? Why or why not?

A) It is feasible. The three metallic ions each receive an electron from sulfur.
B) No, it is not feasible. Sulfur cannot give three electrons to the metal since the sulfide ion has a -2 charge.
C) No, it is not feasible. The metallic ion X only has one valence electron and the sulfide ion receives two electrons.
D) No, it is not feasible. Three metallic ions cannot provide the exact number of electrons that one sulfur needs for the ionic bond.

Answer 1

The correct answer is D) No, it is not feasible. Three metallic ions cannot provide the exact number of electrons that one sulfur needs for the ionic bond.

Step-by-step explanation:

I just took the test from USATESTPREP.

Answer 2

The answer is D. No, it is not feasible. Three metallic ions cannot provide the exact number of electrons that one sulfur needs from the ionic bond.

Sulfur is found in Group 6A, which means that it needs two electrons to form an octet for bonding. In order for it to form an ionic bond it should receive the same number of electrons it is missing. The metallic ion X cannot give 3, because that would mean there would be an excess each time. As such, the formula X3S will not be feasible.
