An artifical transmutation was carried out on ._(7)^(14)N by an alpha-particle which resulted in an unstable nuclide and a proton. What is the ratio of the atmoic mass to be atomic number of the unstable nuclide?

Answer»

`(17)/(8)`
`(15)/(7)`
`(17)/(9)`
`(15)/(8)`

Solution :`._(7)^(14)N + ._(2)^(4)He to ._(8)^(17)O + ._(1)^(1)H`
`("MASS NUMBER")/("Atomic Number") = (17)/(8)`
