The given datas areSample      Protons   Neutrons   Electrons       Mass No(protons + neutrons)A                     19             20               16                 39B                     18             19               18                 37C                     17             20               17                 37D                     17             17               17                 34a) Cations have less number of electrons than protonsSo A exist as A3+ (as three electrons are less than protons)b) Isobars are formed if pairs of an element has same mass number
So B and C are isobarsc) Isotpes means the number of protons are sameC and D are isotopes
