प्रश्न
Write down the electronic configuration of the following:
(a) `""_13^27"Y"`
(b) `""_17^35"Y"`
Advertisements
उत्तर
Electronic configuration: 27X13 = 2, 8, 3
Number of electrons in X = 13
Number of neutrons in X = 27 - 13 = 14
Electronic configuration of 35Y17 = 2, 8, 7
Number of electrons in Y = 17
Number of neutrons in Y = 35 - 17 = 18
