Vhich statement best describes how many chlorine atoms are needed when making Barium chloride? O2 chlorine atoms are needed because each chlorine atom accepts one of bariums two valence electrons to obtain a full octet and makes chlorine a negatively charged anion. 1 chlorine atom is needed because chlorine accepts one electron from barium to obtain a full octet and makes chlorine a negatively charge anion. 1 chlorine atom is needed because chlorine accepts one electron from barium to obtain a full octet and makes chlorine a positively charged cation. 2 chlorine atoms are needed because each chlorine atom accepts one of bariums two valence electrons to obtain a full octed and makes chlorine a positively charged anion.

Which of the following is/are the most significant resonance structure(s)? H H III I O II and III O they are equivalent O.III OI CO II II
