In which of these case do we have enough information to say that the atom is electrically neutral?

I believe I know the full question, I had this one as well.

The answer is:

A. "The atom has 7 protons and 7 electrons. -here we have enough information to say that the atom is electrically neutral."

2b2t

explanation:

2b2t

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
