1.	30. X, Y2and Z are isoelectronic of CO2. Increasingorder of protons in X.Y+ and Z is(3) ZXY
Answer» CO2 has --- 6+8+8 electrons = 22 electrons so, X+ , Y2+ and Z- should also have 22 electrons => proton of X = 22+1( +ve charge) = 23=> proton of Y = 22+ 2( +2 ve charge) =24=> proton of z = 22-1 ( -ve charge) =21 so, correct order is Y2+ > X+ > Z-option 3

30. X, Y2and Z are isoelectronic of CO2. Increasingorder of protons in X.Y+ and Z is(3) ZXY

Answer»

CO2 has --- 6+8+8 electrons = 22 electrons

so, X+ , Y2+ and Z- should also have 22 electrons

=> proton of X = 22+1( +ve charge) = 23=> proton of Y = 22+ 2( +2 ve charge) =24=> proton of z = 22-1 ( -ve charge) =21

so, correct order is Y2+ > X+ > Z-option 3
