Elements in group 6A (16) have a -2 charge when they are in compounds. Which of the following statements best explains the reason for this observation?
A) These elements accept two electrons to increase in energy.
B) These elements donate two electrons during the bonding process.
C) These elements accept two electrons so that their valence shells are full.
D) These elements donate two electrons to minimize their mass.
E) There is no way to rationalize this; it is just an observation.

Question

Quizplus · Accepted Answer

Group 6A (16) elements have six valence electrons, and by accepting two more electrons, they can complete their valence shell and attain noble gas configuration. This forms a negatively charged ion, represented by the F1F1F1S1F1F1F102 charge.
