When neutron is transformed into a proton during the nuclear transformation, which of the following is produced ?
Answer: D
When a neutron turns into a proton, negative beta rays are produced.
In beta-minus decay a neutron in the nucleus changes into a proton, emitting an electron (a negative beta particle) and an antineutrino. The atomic number rises by one, while the mass number stays the same.
Positive beta (positron) emission is the reverse, a proton becoming a neutron. Alpha decay emits a helium nucleus, and gamma rays are photons released when a nucleus drops to a lower energy state; neither involves a neutron becoming a proton.
