Pick out the isobar of 18Ar^40.(a) 12Mg^24(b) 26Fe^58(c) 19K^40(d) 28N

1.	Pick out the isobar of 18Ar^40.(a) 12Mg^24(b) 26Fe^58(c) 19K^40(d) 28Ni^64This question was addressed to me in a job interview.My enquiry is from Atomic Models topic in chapter Structure of Atom of Chemistry – Class 11
Answer» Correct choice is (c) 19K^40 The BEST I can explain: Isobar is a species of an element having the same mass number but a DIFFERENT atomic number. As per the above QUESTION, only 19K^40 satisfies the conditions of 18Ar^40 to be its ISOTOPE.
