Question
A positron is emitted from 23Na11 . The ratio of the atomic mass and atomic number of the resulting nuclide is
Options
A.22/10
B.22/11
C.23/10
D.23/12
Solution
On position emission from nucleus, proton converts into neutron therefore atomic number decreases by one but atomic mass remains constant.
Hence (C) is correct.
Hence (C) is correct.
