Mg-20 parent nuclide would give rise to the daughter nuclide Na-20 by positron emission. Option E
This is further explained below.
Generally, A nuclide is a specific kind of atom that can be recognized by the number of protons in its nucleus, which is denoted by the symbol Z, the number of neutrons in its nucleus, which is denoted by the symbol N, and the nuclear energy state.
The term "nuclide" wasn't coined until 1947, when Truman P. Kohman was the one who first used it.
In conclusion, Through the process of positron emission, the parent nuclide Mg-20 would eventually give way to the daughter nuclide Na-20. Alternative E
