88R226 Experiences three a - decay. Find the number of neutrons in the daughter element. |
|
Answer» Mass number of 88Ra226 is 266 Atomic number of 88Ra226 is 88 Mass number of α = 4 Atomic number of α = 2 After 3 a decay Mass number of the daughter element is = 226 – (3 × 4) = 226 – 12 = 214 Atomic number of the daughter element is = 88 – (3 × 2) = 88 – 6 = 82 Number of neutrons is = 214 – 82 = 132 |
