Which of the following is not a way an atom can achieve stability?

a. lose electrons to achieve a noble gas configuration
b. share electrons to abide by the octet rule
c. gain electrons to fill its outer energy level
d. remove electrons from its full outer energy level

The answer is D. An atom WANTS to have a full outer energy level, or to form strong bonds to achieve stability. The answer can't be C, because filling the outermost energy level will make the atom the most stable.

Answer    "a salt" would be the best answerexplanationsalts can be defined as ionic compounds that are neither acids nor bases. nacl is an example of a salt, and its ionic.an enzyme is an organic compound which is covalently bonded, not ionically bonded.acids are generally held together by covalent bondsan element does not need any bonds to exist
