Expert Answer
Energy level En of hydrogen like atom for orbital quantum number n is given by
.......................(1)First line of Lyman series in hydrogen is due to transition from n=2 to n=1
Hence energy difference for first line of Lyman seriesis in hydrogen atom given by
.................. (2)Second line of Balmer series in hydrogen-like atom is due to transition from n=4 to n=2
Hence energy difference for second line of Balmer series in hydrogen-like atom is given by
..................(3)By equating equations (2) and (3), we get z = 2
