[QUOTE="Ryan, post: 2643794, member: 211099"] I just got my quiz back for chemistry today and I don't understand why I got one of the answers wrong. The question is: The similar chemical behavior of the elements in a given group in the periodic table is best accounted for by the fact that these elements have: A) the same number of electrons B) The same number of electrons in the valence shell C) similar nuclear structures D) the same number of protons E) the same number of isotopes. I put C. She wouldn't explain to me why it was wrong so can someone help? (no this isn't homework I already did the quiz so don't give me crap about it ) [/QUOTE]
