Electrinoic configuration of species M^(2+) is 1s^(2) 2s^22p^63s^23p^6

1.	Electrinoic configuration of species M^(2+) is 1s^(2) 2s^22p^63s^23p^63d^6 and its atomic weight is 56.The number of neutrons in the nuclcus of species M Is…………..
Answer» 26 22 30 24 Solution :`M^(2+)`:`1s^2``2s^2``2p^6``3s^2``3p^6``3d^6` M:`Is^2``2s^2``2p^6``3s^2``3p^6``3d^8` ATOMIC number=26 Mass number=56 No.of netutrons=56-26=30
